DESCRIPTION
The 74LVQ573 is a low voltage CMOS OCTAL
D-TYPE LATCH with 3 STATE OUTPUTS NON
INVERTING fabricated with sub-micron silicon
gate and double-layer metal wiring C
technology. It is ideal for low power and low noise
3.3V applications.
These 8 bit D-Type latch are controlled by a latch
enable input (LE) and an output enable input (OE).

Table 1: Order Codes
While the LE input 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 high level the outputs will be in a high
impedance state. In order to enhance PC board
layout, the 74LVQ573 offers a pinout having inputs
and outputs on opposite side of the package.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
