DESCRIPTION
The 74VHC573 is an advanced high-speed
CMOS OCTAL D-TYPE LATCH with 3 STATE
OUTPUTS NON INVERTING fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
These 8 bit D-Type latch are controlled by a latch
enable input (LE) and an output enable input (OE).
While the LE inputs is held at a high level, the Q
outputs will follow the data input 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 (OE) is in 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
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
