TECHNICAL DATA

IW4034B

8-Stage Static Bidirectional Parallel/
Serial Input/Output Bus Register

High-Voltage Silicon-Gate CMOS

The IW4034B 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 two buses, 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-TO-B-BUS/ B­BUS-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) dependung 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 inputs generated
internally to allow synchronous or asynchronous data transfer from
master to slave.
