KK74AC574

TECHNICAL DATA Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS KK74AC574 The KK74AC574 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 ORDERING INFORMATION KK74AC574N Plastic KK74AC574DW SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND FUNCTION TABLE Output Enable L L L Inputs Clock L,H, HX X = don’t care Z = high impedance Output DQ HH LL X no change XZ 1 KK74AC574 MAXIMUM RATINGS* Symbol Parameter Value VCC VIN VOUT IIN IOUT ICC PD DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ -0.5 to +7.0 -0.5 to VCC +0.5 -0.5 to ...
