TECHNICAL DATA
KK74ACT574
Octal 3-State Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
The KK74ACT574 is identical in pinout to the LS/ALS574, HC/HCT574. The KK74ACT574 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. 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. • TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 4.5 to 5.5 V • Low Input Current: 1.0 µA; 0.1 µA @ 25°C • 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.
