74LVTH32952

Low Voltage 32-Bit Registered Transceiver

with 3-STATE Outputs (Preliminary)

General Description

The LVTH32952 is a 32-bit registered transceiver. Four

8-bit back to back registers store data flowing in both direc-

tions between two bidirectional buses. Separate clock,

clock enable, and output enable signals are provided for

each register.

The LVTH32952 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

The registered transceiver is designed for low voltage

(3.3V) V

TTL interface to a 5V environment.

The LVTH32952 is fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining low power dissipation.

Ordering Code:
