TXS0102YZPR 2-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Applications DSBGA8 spot stock

Product Descriptions

This two-bit non-inverting translator is a bidirectional  voltage-level translator and can be used to establish  digital switching compatibility between mixed-voltage  systems. It uses two separate configurable powersupply rails, with the A ports supporting operating  voltages from 1.65V to 3.6V while it tracks the VCCA  supply, and the B ports supporting operating voltages  from 2.3V to 5.5V while it tracks the VCCB supply.  This allows the support of both lower and higher logic  signal levels while providing bidirectional translation  capabilities between any of the 1.8V, 2.5V, 3.3V, and  5V voltage nodes.

When the output-enable (OE) input is low, all I/Os  are placed in the high-impedance state, which  significantly reduces the power-supply quiescent  current consumption.

To put the device in the high-impedance state during  power up or power down, tie OE to GND through  a pulldown resistor; the current-sourcing capability  of the driver determines the minimum value of the  resistor.

Product Features

• No direction-control signal needed
