IN74AC574 Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS

Octal 3-State Noninverting D Flip-Flop

High-Performance Silicon-Gate CMOS    

The IN74AC574 is identical in pinout to the LS/ALS574, HC/HCT574. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.

Data meeting the setup time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, all device outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled.

• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 μA; 0.1 μA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA
