General description

The 74LVTH32245 is a high-performance BiCMOS product designed for VCC operation at

3.3 V. The 74LVTH32245 is a 32-bit transceiver featuring non-inverting 3-state bus

compatible outputs in both send and receive directions. The device features four output

enable (nOE) inputs for easy cascading and four send/receive (nDIR) inputs for direction

control. Pin nOE controls the outputs so that the buses are effectively isolated. Bus hold

on data inputs eliminates the need for external pull-up resistors to hold unused inputs.
