MC14021B

MC14014B, 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 R...
