Preliminary
CMOS 8-STAGE STATIC
SHIFT REGISTERS
„ DESCRIPTION
The UCD4021B 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. In
UCD4021B serial entry is synchronous with the clock but parallel
entry is asynchronous.
In UCD4021B 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, asynchronous parallel entry is made and the
CLOCK input of the internal stage is isolated.
„ 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

Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
