Octal D-Type Positive Edge-Triggered

Flip-Flop with 3-State Outputs

GENERAL DESCRIPTION

FEATURES

The 74HC574 is an octal D-Type positive edge-triggered

flip-flop with 3-state outputs. The device can accept a

wide supply voltage range from 2.0V to 5.5V.

● Wide Supply Voltage Range: 2.0V to 5.5V

● +7.8mA/-7.8mA Output Current

● 8-Bit Positive Edge-Triggered Register

● 3-State Non-Inverting Outputs Suitable for

Bus-Oriented Applications

��

OE is output enable input and CP is clock input. When

��

OE sets high, the outputs are in a high-impedance

● CMOS Low Power Consumption

● -40℃ to +125℃ Operating Temperature Range

● Available in Green TSSOP-20 and SOIC-20

Packages

state. OE does not affect internal operations of the

flip-flop. Old data can be retained or new data can be

entered while the outputs are in the high-impedance

state.
