Product Summary

The HEF4021B is an 8-bit static shift register(parallel-to-serial converter) with a synchronous serialdata input (DS), a clock input (CP), an asynchronous activeHIGH parallel load input (PL), eight asynchronous paralleldata inputs (P0 to P7) and buffered parallel outputs fromthe last three stages.
