DESCRIPTION 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.
Inputs that control the operations include a single-phase CLOCK (CL), A DATA ENABLE (AE), ASYNCHRONOUS/SYNCHRONOUS (A/S), A-BUS-TOB-BUS/B-BUS-TO-A-BUS (A/B), and PARALLEL/ SERIAL (P/S).
Data inputs include 16 bidirectional parallel data lines of which the eight A data lines are inputs (3-state outputs) and the B data lines are outputs (inputs) depending on the signal level on the A/B input.
In addition, an input for SERIAL DATA is also provided.
All register stages are D-type masterslave flip-flops wi...
