TECHNICAL DATA
Octal 3-State
Noninverting D Flip-Flop
IN74AC574
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

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
