MC74HC164A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Bit Serial-Input/ Parallel-Output Shift Register High–Performance Silicon–Gate CMOS The MC54/74HC164A 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 MC54/74HC164A 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. 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 µA 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 1 2 DATA MC54/74HC164A J SUFFIX CERAMIC PACKAGE CASE 632–08 1 14 14 1 N SUFFIX PLASTIC PACKAGE CASE 646–06 14 1 D SUFFIX SOIC PACKAGE CASE 751A–03 14 1 DT SUFFIX TSSOP PACKAGE CASE 948G–01 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXAD MC74HCXXXADT Ceramic Plastic SOIC TSSOP A1 A2 3 4 5 6 10 11 12 CLOCK 8 13 QA QB QC QD QE QF QG QH PARALLEL DATA OUTPUTS PIN ASSIGNMENT A1 A2 QA QB QC 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC QH QG QF QE RESET CLOCK RESET 9 PIN 14 = VCC PIN 7 = GND QD GND FUNCTION TABL...
