DESCRIPTION
The 74VCXH162373 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 high
speed 2.3 to 3.6V applications; it can be interfaced
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 will be in a high
impedance state. Bus hold on data inputs is
provided in order to eliminate the need for external
pull-up or pull-down resistor. The device circuits is
including 26
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 immunity and transient excess
voltage.
