TECHNICAL DATA
KK74HC574A
Octal 3-State Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
N SUFFIX PLASTIC DIP
The KK74HC574A is identical in pinout to the LS/ALS574. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. Data meeting the setup time is clocked to the outputs with the rising edge of the Clock. The OE input does not affect the states of the flip-flops, but when OE 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 A High Noise Immunity Characteristic of CMOS Devices

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.
