TECHNICAL DATA
8-Stage Static Bidirectional Parallel/
Serial Input/Output Bus Register
High-Voltage Silicon-Gate CMOS
IW4034B
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/ 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) 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.
• Operating Voltage Range: 3.0 to 18 V
• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
• Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

* Outputs change at positive transition of clock in the serial mode and when the A/S control input is “low” in the
parallel mode. During transfer from parallel to serial operation A/S should remain low in oder to prevent DS transfer
into Flip Flops.

PARALLEL OPERATION
A high P/S input signal allows data transfer into the register via the parallel data lines synchronously with the
positive transition of the clock provided the A/S input is low. If the A/S input is high the transfer is independent of the
clock. The direction of data flow is controlled by the A/B input. When this signal is high the A data lines are inputs
(and B data lines are outputs); a low A/B signal reverses the direction of data flow.
The AE input is an additional feature which allows many registers to feed data to a common bus. The A DATA
lines are enabled only when this signal is high.
Data storage through recirculation of data in each register stage is accomplished by making the A/B signal high
and the AE signal low.
SERIAL OPERATION
A low P/S signal allows serial data to transfer into the register synchronously with the positive transition of the
clock. The A/S input is internally disabled when the register is in the serial mode (asynchronous serial operation is not
allowed).
The serial data appears as output data on either the B lines (when A/B is high) or the A lines (when A/B is low
and the AE signal is high).
