8-Bit Static Shift Register
MC14014B
MC14021B
The MC14014B and MC14021B 8–bit static shift registers are constructed
with MOS P–channel and N–channel enhancement mode devices in a single
monolithic structure. These shift registers find primary use in parallel–to–
serial data conversion, synchronous and asynchronous parallel input, serial
output data queueing; and other general purpose register applications
requiring low power and/or high noise immunity.
