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_CC applications, but with the capability to provide a
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.
