STMicroelectronics HCC4034B
The HCC4034B (extended temperature range) and HCF4034B (intermediate temperature range) are monolithic integrated circuits, available in 24-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4034B is a static eight-stage parallel-or serial-input parallel-output register. It can be used to : 1) bidirectionally transfer parallel information between two buses ; 2) convert serial data to parallel form and direct the parallel data to either of twobuses ; 3) store (recirculate) parallel data, or 4) accept parallel data from either of two buses and convert that data to serial form.
