74LCXH16373 Low Voltage 16-Bit Transparent Latch with Bushold
February 2001
Revised August 2001
74LCXH16373
Low Voltage 16-Bit Transparent Latch with Bushold
General Description
The LCXH16373 contains sixteen non-inverting latches
with 3-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. The flip-flops
appear 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 outputs are in
a high impedance state.
The LCXH16373 is designed for low voltage (2.5V or 3.3V)
V
CC
applications with capability of interfacing to a 5V signal
environment.
The LCXH16373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
The LCXH16373 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data input at a valid logic level.
