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) par-
allel 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), ASYN-
CHRONOUS/SYNCHRONOUS (A/S), A-BUS-TO-
B-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 out-
puts (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 master-
slave flip-flops with separate master and slave clock
