D flip-flop with CLR input
This D flip-flop is an edge-triggered D flip-flop with an additional input CLR (clear), via which the internal state can be set directly to 0.
Truth table
| CLR | C | D | Q1 | Q2 |
|---|---|---|---|---|
| 1 | x | x | 0 | 1 |
| 0 | ↑ | 0 | 0 | 1 |
| 0 | ↑ | 1 | 1 | 0 |
| 0 | x | x | q1 | q2 |
Comments:
x = any (0 or 1) ↑ = positive edge from 0 to 1 q = state of output Q remains unchanged
