KK74HC534A

TECHNICAL DATA KK74HC534A Octal 3-State Inverting D Flip-Flop High-Performance Silicon-Gate CMOS The KK74HC534A is identical in pinout to the LS/ALS534. 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, in inverted form, 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, the 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 High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC534AN Plastic KK74HC534ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 20=VCC PIN 10 = GND Output Enable L L L H L,H, X Clock D H L X X Output Q L H no change Z X = don’t care Z = high impedance www.DataSheet4U.net 1 KK74HC534A MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter 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 Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds...
