The ADG2412 contains four independent single-pole/single-throw (SPST) switches. The ADG2412 switches turn on with logic 1 on the digital control inputs. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends from VSSto VDD− 2 V. When switches are open, signal levels up to the supplies are blocked.The digital inputs are compatible with 5 V, 3.3 V, and 1.8 V logic inputs without the requirement for a separate digital logic supply pin.The on-resistance profile is exceptionally flat over the full-analog input range, which ensures good linearity and low distortion when switching audio signals.PRODUCT HIGHLIGHTSLow RONof 0.5 Ω.High continuous current carrying capability, see Table 5 to Table 8.Dual-supply operation.

The ADG3123 is an 8-channel, noninverting CMOS to high voltage level translator. Fabricated on an enhanced LC2MOS process, the device is capable of operating at high supply voltages while maintaining ultralow power consumption.The internal architecture of the device ensures compatibility with logic circuits running from supply voltages within the 2.3 V 5.5 V range. The voltages applied to Pin VDDA, Pin VDDBand Pin VSSset the logic levels available at the outputs on the Y side of the device. Pin VDDAand Pin VDDBset the high output level for Pin Y1 to Pin Y6 and for Pin Y7 to Pin Y8, respectively. The VSSpin sets the low output level for all channels. The ADG3123 can provide output voltages levels down to −24.2 V for a low input level and up to +35 V for a high input logic level. For proper operation, VDDBmust always be greater than or equal to VDDAand the voltage between the Pin VSSand Pin VSSshould not exceed 35 V.The low output impedance of the channels guarantees fast rise and fall times even for significant capacitive loads. This feature, combined with low propagation delay and low power consumption, makes the ADG3123 an ideal driver for TFT-LCD panel applications.The ADG3123 is guaranteed to operate over the −40°C to +85°C temperature range and is available in a compact, 20-lead TSSOP, Pb-free package.PRODUCT HIGHLIGHTSCompatible with a wide range of CMOS logic levels.High output voltage levels.Fast rise and fall times coupled with low propagation delay.Ultralow power consumption.Compact, 20-lead TSSOP, RoHS-compliant package.APPLICATIONSLow Voltage to High Voltage TranslationTFT-LCD PanelsPiezoelectric Motor Drivers

The ADG3233 is a bypass switch designed on a submicron process which operates from supplies as low as 1.65 V. The device is guaranteed for operation over the supply range 1.65 V to 3.6 V. It operates from two supply voltages allowing bidirectional level translation, that is. it translates low voltages to higher voltages and vice versa. The signal path is unidirectional, meaning data may only flow from A to Y.This type of device may be used in applications that require a bypassing function. It is ideally suited to bypassing devices in a JTAG chain or bypassing devices in a daisy-chain loop. One switch could be used for each device or a number of devices, thus allowing easy bypassing of one or more devices in a chain. This may be particularly useful in reducing the time overhead in testing devices in the JTAG chain or in daisy-chain applications where the user does not wish to change the settings of a particular device.The bypass switch is packaged in two of the smallest footprints available for its required pin count. The 8-lead SOT-23 package requires only 2.9 mm x 2.8 mm board space, while the MSOP package occupies approximately 3 mm x 4.9 mm board area.

The ADG3243 is a 2.5 V or 3.3 V, 2-bit, 2-port digital switch with individual channel control. It is designed on a low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance. This allows the inputs to be connected to the outputs without additional propagation delay or generating additional ground bounce noise.The switches are enabled by means of the bus enable (BEx) input signal. This digital switch allows a bidirectional signal to be switched when ON. In the OFF condition, signal levels up to the supplies are blocked.This device is ideal for applications requiring level translation. When operated from a 3.3 V supply, level translation from 3.3 V inputs to 2.5 V outputs is allowed. Similarly, if the device is operated from a 2.5 V supply and 2.5 V inputs are applied, the device will translate the outputs to 1.8 V. This makes the device suited to applications requiring level translation between different supplies, such as converter to DSP/microcontroller interfacing.APPLICATIONS3.3 V to 2.5 V Voltage Translation2.5 V to 1.8 V Voltage TranslationBus SwitchingBus IsolationHot SwapHot PlugAnalog Switch ApplicationsPRODUCT HIGHLIGHTS3.3 V or 2.5 V supply operation.Extremely low propagation delay through switch.4.5 Ω switches connect inputs to outputs.Level/voltage translation.Tiny SOT-23 package.

The ADG3245 is a 2.5 V or 3.3 V, 8-bit, 2-port digital switch. It is designed on Analog Devices’ low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance, allowing inputs to be connected to outputs without additional propagation delay or generating additional ground bounce noise.The switches are enabled by means of the bus enable (BE) input signal. These digital switches allow bidirectional signals to be switched when ON. In the OFF condition, signal levels up to the supplies are blocked.This device is ideal for applications requiring level translation. When operated from a 3.3 V supply, level translation from 3.3 V inputs to 2.5 V outputs is allowed. Similarly, if the device is operated from a 2.5 V supply and 2.5 V inputs are applied, the device will translate the outputs to 1.8 V. In addition to this, a level translating select pin (SEL) is included. WhenSELis low, VCC is reduced internally, allowing for level translation between 3.3 V inputs and 1.8 V outputs. This makes the device suited to applications requiring level translation between different supplies, such as converter to DSP/microcontroller interfacing.APPLICATIONS3.3 V to 1.8 V voltage translation3.3 V to 2.5 V voltage translation2.5 V to 1.8 V voltage translationBus switchingBus isolationHot swapHot plugAnalog switch applicationsPRODUCT HIGHLIGHTS3.3 V or 2.5 V supply operationExtremely low propagation delay through switch4.5 Ω switches connect inputs to outputsLevel/voltage translation20-lead TSSOP and LFCSP (4 mm × 4 mm) packages
