74LCX32646

Low Voltage 32-Bit Transceiver/Register

with 5V Tolerant Inputs and Outputs (Preliminary)

General Description

The LCX32646 contains thirty-two non-inverting bidirec-

tional registered bus transceivers with 3-STATE outputs,

providing multiplexed transmission of data directly from the

input bus or from the internal storage registers. Each byte

has separate control inputs which can be shorted together

HIGH transition (see Functional Description).

The LCX32646 is designed for low voltage (2.5V or 3.3V)

environment.

The LCX32646 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.
