DESCRIPTION
The 74VHCT16373A is an advanced high-speed
CMOS 16 BIT D-TYPE LATCH with 3 STATE
OUTPUTS NON INVERTING fabricated with
sub-micron silicon gate and double-layer metal
wiring C
These 16 bit D-TYPE latches are byte controlled
by two latch enable inputs (nLE) and two output
enable inputs(nOE).
While the nLE input is held at a high level, the nQ
outputs will follow the data (D) inputs.
When the nLE is taken LOW, the nQ outputs will
be latched at the logic level of D data inputs.
When the (nOE) input is low, the nQ outputs will
be in a normal logic state (high or low logic level);
when nOE is at high level ,the outputs will be in a
high impedance state.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
