CMOS 8-STAGE STATIC SHIFT

REGISTERS

DESCRIPTION

The UTC UCD4014B is a 8-stage synchronous parallel or serial

input/serial

output

registers

having

common

CLOCK

and

PARALLEL/SERIAL CONTROL inputs, a SERIAL data input, and

individual parallel inputs to each register stage. Each register is a

D-type master-slave flip-flop. Q6, Q7, and Q8 are outputs. With the

positive clock line transition in the UCD4014B parallel/serial entry is

made into the register synchronously.

In

UCD4014B

serial

entry

is

controlled

by

the

PARALLEL/SERIAL CONTROL input. When the PARALLEL/SERIAL

CONTROL input is low, data is serially shifted into the 8-stage register

synchronously with the positive transition of the clock line. When the

PARALLEL/SERIAL CONTROL input is high, data is jammed into the

8-stage register via the parallel input lines and synchronous with the

positive transition of the clock line.

FEATURES

* Up to 20V operation voltage

* 12MHz (typ.) clock rate at 10V

* Maximum input current of 1μA at 18V

* Fully static operation

* 8 master-slave flip-flops plus output buffering and control gating

APPLICATIONS

* General-purpose register

* Parallel input/serial output data queueing

* Parallel to serial data conversion
