FEATURES
DESCRIPTION
The 74LVC373A 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 3.3V or 5V devices. In 3-State
operation, outputs can handle 5V. This feature allows the use of
these devices as translators in a mixed 3.3V/5V environment.

The 74LVC373A 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.
true outputs. When LE is HIGH, data at the D
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 setup 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 ’373’ is functionally identical to the ’573’, but the ’573’ has a
different pin arrangement.
The ’373’ consists of eight D-type transparent latches with 3-State
