1. General description

The 74AVCH1T45 is a single bit, dual supply transceiver that enables bidirectional level translation.

The 74AVCH1T45 has active bus hold circuitry which is provided to hold unused or floating data

inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down

resistors.The device is fully specified for partial power-down applications using IOFF. The IOFF

circuitry disables the output, preventing potentially damaging backflow current through the device

when it is powered down.
