1. General description
The 74LVC574A is an octal D-type flip-flop featuring separate D-type inputs for each
flip-flop and 3-state outputs for bus-oriented applications. A clock (CP) and an Output
Enable (OE) input are common to all flip-flops.
The eight flip-flops will store the state of their individual D-inputs that meet the set-up and
hold times requirements on the LOW to HIGH CP transition.
When OE is LOW, the contents of the eight flip-flops are available at the outputs. When
OE is HIGH, the outputs go to the high-impedance OFF-state. Operatio n of the OE input
does not affect the state of the flip-flops.
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 74LVC574A is functionally identical to the 74LVC374A, but has a different pin
arrangement.
2. Features and benefits

5.1 Pinning
5.2 Pin description
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
