CMOS 8-STAGE STATIC SHIFT REGISTERS
- DESCRIPTION
The UCD4021B is a 8-stage synchronous parallel or serial input/serial output registers having mon 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...
