DESCRIPTION
The 74VCXH16373 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
2
MOS
technology. It is ideal for low power and very hi gh
speed 2.3 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 w ill 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.
Bus hold on data inpu ts is provided in order to
eliminate the need for exte rnal pull-up or
pull-down resistor.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunit y and transient ex c ess
voltage.
