The ADG3247 is a 2.5 V or 3.3 V 16-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 ADG3247 is organized as dual 8-bit bus switches with separate bus enable (BEx) inputs. This allows the device to be used as two 8-bit digital switches or one 16-bit bus switch. These bus switches allow 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 occurs. 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, the ADG3247 has a level translating select pin (SEL). WhenSELis low, VCCis 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 PlugHot SwapAnalog Switching ApplicationsProduct Highlights3.3 V or 2.5 V supply operationExtremely low propagation delay through switch4.5 Ω switches connect inputs to outputsLevel/voltage translation38-lead TSSOP package

The ADG3304 is a bidirectional logic level translator that contains four bidirectional channels. It can be used in multivoltage digital system applications such as data transfer between a low voltage DSP/controller and a higher voltage device using SPI and MICROWIRE interfaces. The internal architecture allows the device to perform bidirectional logic level translation without an additional signal to set the direction in which the translation takes place.The voltage applied to VCCAsets the logic levels on the A side of the device, while VCCYsets the levels on the Y side. For proper operation, VCCAmust always be less than VCCY. The VCCA-compatible logic signals applied to the A side of the device appear as VCCY-compatible levels on the Y side. Similarly, VCCY-compatible logic levels applied to the Y side of the device appear as VCCA-compatible logic levels on the A side.The enable pin (EN) provides three-state operation on both the A-side and the Y-side pins. When the EN pin is pulled low, the terminals on both sides of the device are in the high impedance state. The EN pin is referred to the VCCAsupply voltage and driven high for normal operation.The ADG3304 is available in compact 14-lead TSSOP, 12-ball WLCSP and 20-lead LFCSP. It is guaranteed to operate over the 1.15 V to 5.5 V supply voltage range.Supports defense and aerospace applications (AQEC standard).ApplicationsSPI, MICROWIRE level translationLow voltage ASIC level translationSmart card readersCell phones and cell phone cradlesPortable communication devicesTelecommunications equipmentNetwork switches and routersStorage systems (SAN/NAS)Computing/server applicationsGPSPortable POS systemsLow cost serial interfaces

The ADG333A is a monolithic complementary metal-oxide semiconductor (CMOS) device comprising four independently selectable single-pole, double-throw (SPDT) switches. It is designed on a linear compatible CMOS (LC2MOS) process, which provides low power dissipation yet achieves a high switching speed and a low on resistance.The on-resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals. High switching speed also makes the device suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the device ideally suited for portable, battery-powered instruments.When they are on, each switch conducts equally well in both directions and has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Low charge inject is inherent in the design.Product HighlightsExtended signal range. The ADG333A is fabricated on an enhanced LC2MOS process, giving an increased signal range which extends to the supply rails.Low power dissipation.Low RON.Single-supply operation. For applications in which the analog signal is unipolar, the ADG333A can be operated from a single rail power supply. The device is fully specified with a single 12 V supply.ApplicationsAudio and video switchingBattery-powered systemsTest equipmentCommunication systems
