KK74HC574A

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 µA High Noise Immunity Characteristic of CMOS Devices 20 1 20 1 DW SUFFIX SOIC ORDERING INFORMATION KK74HC574AN Plastic DIP KK74HC574ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM OE D0 D1 D0 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 CLOCK 2 3 4 5 6 7 8 9 11 19 18 17 16 15 14 13 12 Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 NONINVERTING OUTPUTS 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 V CC Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 CLOCK D2 D3 D4 D5 D6 D7 GND FUNCTION TABLE Inputs Output D H L L,H, X 1 OE OE L Clock Q H L no change Z PIN 20=VCC PIN 10 = GND L L H X X H= high level L = low level X = don’t care Z = high impedance www.DataSheet4U.net 1 KK74HC574A MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenc...
