DESCRIPTION
The HCF4021B is a monolithic integrated circuitfabricated in Metal Oxide Semiconductortechnology available in DIP and SOP packages. This device is an 8-stage parallel or serial input/serial output register having common CLOCK andPARALLEL/SERIAL CONTROL inputs, a singleSERIAL data input, and individual parallel \"JAM\"inputs to each register stage. Each register stageis a D-type, master-slave flip-flop in addition to anoutput from stage 8, \"Q\" outputs are also availablefrom stages 6 and 7. Serial entry is synchronouswith the clock but parallel entry is asynchronous.PIN CONNECTIONIn this device, entry is controlled by thePARALLEL/SERIAL CONTROL input. When thePARALLEL/SERIAL CONTROL input is low, datais serially shifted into the 8-stage registersynchronously with the positive transition of heclock line. When the PARALLEL/SERIALCONTROL input is high, data is jammed into the8-stage register via the parallel input lines andsynchronous with the positive transition of theclock line, the CLOCK input of the internal stage is\"forced\" when asynchronous parallel entry ismade. Register expansion using multiple packageis permitted.
