HCC4014B

The HCC/HCF4014B and HCC/HCF4021B (extended temperature range and intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4014B and HCC/HCF4021B seriestypes are 8-stage parallel-or serial-input/serial-output registers having common CLOCK and PARALLEL/ SERIAL CONTROL inputs, a single SERIAL data input, and individual parallel "JAM" inputs to each register stage. Each register stage is a Dtype, master-slave flip-flop in addition to an output from stage 8, "Q" outputs are also available from stages 6 and 7. Parallel as well as serial entry is made into the register synchronously with the positive clock line transition in the HCC/HCF4014B. In the HCC/HCF4021B serial entry is synchronous with the clock but parallel entry is asynchronous. In both types, entry is controlled by thePARALLEL/SERIAL CONTROL input. When the PARALLEL/SERIAL CONTROL input is low, data is serially shifted into the 8-stage register synchronously with the positive transition of the clock line. When the PARALLEL/SERIAL CONTROL input is high, data is jammed into the 8-stage register via the parallel input
