MC74HC164A 8-Bit Serial-Input/ Parallel-Output Shift Register High–Performance Silicon–Gate CMOS The MC74HC164A is identical in pinout to the LS164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The MC74HC164A 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. http://onsemi.com MARKING DIAGRAMS 14 PDIP–14 N SUFFIX CASE 646 MC74HC164AN AWLYYWW 1 14 SOIC–14 D SUFFIX CASE 751A 1 14 TSSOP–14 DT SUFFIX CASE 948G HC 164A ALYW HC164A AWLYWW Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 244 FETs or 61 Equivalent Gates LOGIC DIAGRAM SERIAL DATA INPUTS A1 A2 1 2 DATA 3 4 5 6 10 QA QB QC QD PARALLEL DATA OUTPUTS 1 A = Assembly Location WL or L = Wafer Lot YY or Y = Year WW or W = Work Week PIN ASSIGNMENT A1 A2 QA QB QC QD 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC QH QG QF QE RESET CLOCK CLOCK 8 QE 11 QF 12 QG 13 QH RESET 9 PIN 14 = VCC PIN 7 = GND GND FUNCTION TABLE Inputs Outputs ORDERING INFORMATION Device MC74HC164AN MC74HC164AD ……
