Preliminary
74VCX32373 Low Voltage 32-Bit Transparent Latch with 3.6V Tolerant Inputs and Outputs (Preliminary)

Revised August 2001
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
CC
applications with I/O compatibility up to 3.6V.
The 74VCX32373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
