DESCRIPTION
The 74VHCT573A is an advanced high-speed
CMOS OCTAL D-TYPE LATCH with 3 STATE
OUTPUT NON INVERTING fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
This 8 bit D-Type latch is controlled by a latch
enable input (LE) and an output enable input
(OE).
PIN CONNECTION AND IEC LOGIC SYMBOLS
While the LE input is held at a high level, the Q
outputs will follow the data inputs precisely.
When the LE is taken low, the Q outputs will be
latched precisely at the logic level of D input data.
While the (OE) input is low, the 8 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.
Power down protection is provided on all inputs
and outputs 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
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
