FEATURES
DESCRIPTION
The 74LVC573A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 or 5 V devices. In
3-state operation, outputs can handle 5 V. This feature
allows the use of these devices as translators in a mixed
3.3 or 5 V environment.

The 74LVC573A is an octal D-type transparent latch
featuring separate D-type inputs for each latch and 3-state
outputs for bus-oriented applications. A Latch Enable (LE)
input and an Output Enable (OE) input are common to all
internal latches.
The 74LVC573A consists of eight D-type transparent
latches with 3-state true outputs. When LE is HIGH, data
at the Dn inputs enters the latches. In this condition, the
latches are transparent, i.e. a latch output will change each
time its corresponding D-input changes. When LE is LOW,
the latches store the information that was present at the
D-inputs one set-up time preceding the HIGH-to-LOW
transition of LE. When OE is LOW, the contents of the
eight latches are available at the outputs. When OE is
HIGH, the outputs go to the high impedance OFF-state.
Operation of the OE input does not affect the state of the
latches.
The 74LVC573A is functionally identical to the
74LVC373A, but the 74LVC373A has a different pin
arrangement.
