Product data sheet
1. General description
The 74LVTH32245 is a high-performance BiCMOS product designed for V_CC 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.
