DESCRIPTION
The 74ACT373 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 C
2
MOS
technology.
These 8 bit D-Type latch are controlled by a latch
enable input (LE) and an output enable input (OE
).
When the (LE) input is high , the Q outputs follow
the data (D) inputs . When the (LE) is taken low,
the Q outputs will be latched at the logic levels set
up at the D inputs. When the (OE
) input is low, the
8 outputs will be in a normal logic state (high or
low logic level); when the (OE)
input is high, 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.
