DESCRIPTION
The 74AC373 is a high-speed CMOS OCTAL
D-TYPE LATCH with 3 STATE OUTPUT NON
INVERTING fabricated with sub-micron silicon
gate and double-layer metal wiring C²MOS
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. When the LE is
taken low, the Q outputs will be latched 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); while OE is in high level
the outputs will be in a high impedance state.
This device is designed to interface directly High
Speed CMOS systems with TTL and NMOS
components.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
