74LCXH162373

Low Voltage 16-Bit Transparent Latch

with Bushold and 26

Ω Series Resistor Outputs

General Description

The LCXH162373 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 LCXH162373 is designed for low voltage (2.5V or

signal environment. The 26

Ω series resistor helps reduce

output overshoot and undershoot.

The LCXH162373 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

The LCXH162373 data inputs include active bushold cir-

cuitry, eliminating the need for external pull-up resistors to

hold unused or floating data inputs at a valid logic level.
