SL74HC164 Datasheet | System Logic Semiconductor

8-Bit Serial-Input/Parallel-Output Shift Register High-Performance Silicon-Gate CMOS The SL74HC164 is identical in pinout to the LS/ALS164. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The SL74HC164 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 the Clock 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 SL74HC164N Plastic SL74HC164D 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 Outputs QA QB ...
