DESCRIPTION

The 74VCX162373 is a low voltage CMOS 16 BIT
D-TYPE LATCH with 3 STATE OUTPUTS NON
INVERTING fabricated with sub-micron silicon
gate and five-layer metal wiring C

MOS
technology. It is ideal for low power and very hi gh
speed 1.8 to 3.6V applications; it can be interfac ed
to 3.6V signal environment for both inputs and
outputs.
These 16 bit D-TYPE latches are bite 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
in a normal logic state (high or low logic level) and
while high level the outputs w il l be in a high
impedance state.
The device circuits is including 26Ω series
resistance in the outputs. These resistors permit
to reduce line noise in high speed applications.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunit y and transient ex c ess
voltage.
