DESCRIPTION
The 74LCX16373 is a low voltage CMOS 16 BIT
D-TYPE LATCH with 3 STATE OUTPUTS NON
INVERTING fabricated with sub-micron silicon
gate and double-layer metal wiring C

MOS
technology. It is ideal for low power and high
speed 3.3V applications; it can be interfaced to 5V
signal environment for both inputs and outputs.
These 16 bit D-TYPE latches are byte controlled
by two latch enable inputs (nLE) and two output
enable inputs(OE).
While the nLE input is held at a high level, the nQ
outputs will follow the data input precisely.
When the nLE is taken LOW, the nQ outputs will
be latched precisely at the logic level of D input
data.
While the (nOE) input is low, the nQ outputs will be
in a normal logic state (high or low logic level) and
while high level the outputs will be in a high imped-
ance state.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
