4-Bit PIPO Register
A parallel-in parallel-out register: four D flip-flops sharing a clock capture four input bits simultaneously and hold them.
What You'll Learn
- Store multiple bits on a single clock edge
- Distinguish a register from a latch
- See parallel load and parallel output
How It Works
Four D flip-flops share one clock. On the clock edge each flip-flop captures its data input, so all four bits load in parallel and are held in parallel - a parallel-in, parallel-out register.
