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
