input (OE).
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.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
DESCRIPTION
The LVQ573 is a low voltage CMOS OCTAL

These 8 bit D-Type flip-flops are controlled by a
