3 Description

This 4-bit non-inverting translator uses two separate

configurable power-supply rails. The A port is

designed to track VCCA. VCCA accepts any supply

voltage from 1.65V to 3.6V. VCCA must be less than or

equal to VCCB. The B port is designed to track VCCB.

VCCB accepts any supply voltage from 2.3V to 5.5V.

This allows for low-voltage bidirectional translation

between any of the 1.8V, 2.5V, 3.3V, and 5V voltage

nodes.

When the output-enable (OE) input is low, all outputs

are placed in the high-impedance state.

The TXS0104V is designed so that the OE input

circuit is supplied by VCCA.

For the high-impedance state during power up or

power down, tie OE to GND through a pull-down

resistor; the current-sourcing capability of the driver

determines the minimum value of the resistor.
