KK74HC164A

TECHNICAL DATA KK74HC164А 8-Bit Serial-Input/Parallel-Output Shift Register High-Performance Silicon-Gate CMOS The KK74HC164A is identical in pinout to the LS/ALS164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The KK74HC164A is an 8-bit, serial-input to parallel-output shift register. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. Data is entered on each rising edge of the clock. The active-low asynchronous Reset overrides theClock and Serial Data inputs. 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 KK74HC164АN Plastic KK74HC164АD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs RESET L H PIN 14 =VCC PIN 7 = GND H H CLOCK X A1 A2 X X X X H D D H L Outputs QA QB…QH L… L no change D QAn…QGn D QAn…QGn D = data input X = don’t care QAn - QGn = data shifted from the previous stage on a rising edge at the clock input. www.DataSheet4U.net 1 KK74HC164А 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,...
