MC14021B: 8-Bit Static Shift Register

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.

Features
  • Synchronous Parallel Input/Serial Output (MC14014B)
  • Asynchronous Parallel Input/Serial Output (MC14021B)
  • Synchronous Serial Input/Serial Output
  • Full Static Operation
  • "Q" Outputs from Sixth, Seventh, and Eighth Stages
  • Double Diode Input Protection
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load Over the Rated Temperature Range
  • MC14014B Pin-for-Pin Replacement for CD4014B
  • MC14021B Pin-for-Pin Replacement for CD4021B
  • Pb-Free Packages are Available*
