The FXLH1T45 is a single bit configurable dual-voltage supply translator designed for both uni-directional and bi-directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCAlevel, and the B port tracks the VCCBlevel. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device remains in 3-STATE until both VCCSreach active levels allowing either VCCto be powered-up first. Internal power down control circuits place the device in 3-STATE if either VCCis removed. The Transmit/Receive (T/<span style="text-decoration: overline">R</span>) input determines the direction of data flow through the device. The FXLH1T45 is designed so that the control pin (T/<span style="text-decoration: overline">R</span>) is supplied by VCCA

The FXLP34 is a single translator with two separate supply voltages: VCC1for input translation voltages and VCCfor output translation voltages. The FXLP34 is part of ON Semiconductor's Ultra Low Power (ULP) series of products. This device operates with VCCvalues from 1.0V to 3.6V, and is intended for use in portable applications that require ultra low power consumption. The internal circuit is composed of a minimum of buffer stages, to enable ultra low dynamic power. The FXLP34 is uniquely designed for optimized power and speed, and is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.

The FXLP4555 is a level-shifter analog circuit designed to translate the voltages between a SIM card and an external baseband. A built-in LDO-type DC-DC converter allows the FXLP4555 to drive 1.8V and 3.0V SIM cards. The device fulfills the ISO7816-3 smart-card interface standard as well as GSM 11.11 (11.12 and 11.18) and 3G mobile requirements (IMT-2000/3G UICC standard). The EN pin enables a low-current Shutdown Mode that extends battery life. The card power supply voltage (VCC_C) is selected using a single pin (VSEL).

The FXMA2102 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels.Intended for use as a voltage translator in applications using the I2C bus interface, the input and output voltage levels are compatible with I2C device specification voltage levels. External pull-up resistors are required.The device is designed so that the A port tracks the VCCAlevel and the B port tracks the VCCBlevel. This allows for bi-directional A/B port voltage translation between any two levels from 1.65V to 5.5V. VCCAcan equal VCCBfrom 1.65V to 5.5V. The OE pin is referenced to VCCA.Either VCCcan be powered-up first. Internal power-down control circuits place the device in 3-state if either VCCis removed.The two ports of the device have automatic direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.

This allows for bi-directional A/B port voltage translation between any two levels from 1.65V to 5.5V. VCCAcan equal VCCBfrom 1.65V to 5.5V.Non-preferential power-up means either VCCcan be powered-up first.

Either port may sense an input signal and transfer it as an output signal to the other port.

The FXMAR2104 is a 4-bit high-performance, configurable dual-voltage supply, open-drain translator for bi-directional voltage translation over a wide range of input and output voltages levels. The FXMAR2104 also works in a push-pull environment.Intended for use as a voltage translator in applications using the I2C-Bus® interface, the input and output voltage levels are compatible with I2C device specification voltage levels. Eight internal 10KΩ pull-up resistors are integrated.The device is designed so that the A port tracks the VCCAlevel and the B port tracks the VCCBlevel. This allows for bi-directional A/B port voltage translation between any two levels from 1.65V to 5.5V. VCCAcan equal VCCBfrom 1.65V to 5.5V.Non-preferential power-up means VCCcan be powered-up first.

Either port may sense an input signal and transfer it as an output signal to the other port.

The FXWA9306 is a dual, bi-directional, I2C-bus and SMBus, voltage-level translator with an enable (OE) input that is operational from 1.0V to 3.6V (VCCA) and 1.8V to 5.5V (VCCB) without requiring a direction pin.As with standard I2C-bus systems, the pull-up resistors are required to provide the logic HIGH levels on the translator's bus. The FXWA9306 has a standard open-drain configuration of the I2C bus. The size of these pull-up resistors depends on the system, but each side of the translator must have a pull-up resistor. The device is designed to work with Standard-Mode, Fast-Mode, and Fast Mode Plus I2C-bus devices in addition to SMBus devices. The maximum frequency is dependent on the RC time constant, but generally supports up to 2MHz.All channels have the same electrical characteristics and there is a minimum deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the switch is symmetrical. The translator provides excellent ESD protection to lower voltage devices and at the same time protects less-ESD resistant devices.
