74LVC573ABQ: Octal D-type transparent latch with 5 V tolerant inputs/outputs; 3-state
The 74LVC573A consists of eight D-type transparent latches, featuring separate D-type
inputs for each latch and 3-state true outputs for bus-oriented applications. A Latch
Enable (LE) input and an Output Enable (OE) input are common to all internal latches.
When LE is HIGH, data at the Dn inputs enters the latches. In this condition, the latches
are transparent, that is, 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.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices as translators in
mixed 3.3 V or 5 V applications.
The 74LVC573A is functionally identical to the 74LVC373A, but has a different pin
arrangement.
