74LVX574
Low Voltage Octal D-Type Flip-Flop with
3-STATE Outputs
General Description
The LVX574 is a high-speed octal D-type flip-flop which is
controlled by an edge-triggered clock input (CP) and a buff-
ered common Output Enable (OE) input. When the OE
input is HIGH, the eight outputs are in a high impedance
state. The LVX574 is functionally identical to the LVX374
but with inputs and outputs on opposite sides of the pack-
age. The inputs tolerate up to 7V allowing interface of 5V
systems to 3V systems.
Features
