MC14021BD Datasheet PDF - Motorola

TheMC14014B and MC14021B 8–bitstatic shift registers are constructed withMOS P–channel and N–channel enhancement mode devices in a single monolithicstructure. These shift registers find primary use in parallel–to–serial data conversion, synchronous and asynchronous parallel input, serial outputdata queueing; and other general purpose register applications requiring low power and/or high noise immunity.

●• 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
