SL4034B
8-Stage Static Bidirectional Parallel/
Serial Input/Output Bus Register
High-Voltage Silicon-Gate CMOS
The SL4034B 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.
