Product data sheet
1. General description
The 74LVTH322245 is a high-performance BiCMOS product designed for V_CC operation
at 3.3 V. The 74LVTH322245 is designed with 30 Ω series resistance in both the HIGH
and LOW states of the output. This design reduces line noise in applications such as
memory address drivers, clock drivers, and bus receivers/transmitters. The
74LVTH322245 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.
