74VCX32373

Low Voltage 32-Bit Transparent Latch

with 3.6V Tolerant Inputs and Outputs (Preliminary)

General Description

The VCX32373 contains thirty-two non-inverting latches

with 3-STATE outputs and is intended for bus oriented

applications. The device is byte controlled. The flip-flops

appear to be transparent to the data when the Latch enable

(LE) is HIGH. When LE is LOW, the data that meets the

setup time is latched. Data appears on the bus when the

Output Enable (OE) is LOW. When OE is HIGH, the out-

puts are in a high impedance state.

The 74VCX32373 is designed for low voltage (1.65V to

3.6V) V

The 74VCX32373 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to V
