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
datato eitherof twobuses ;3)store(recirculate) par-
alleldata, or 4) acceptparallel datafrom either oftwo
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 DATAis
also provided. All register stages are D-typemaster-
slaveflip-flops withseparate master and slaveclock
