Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CLR1 | input | Active-low direct clear input for flip-flop 1, independent of the clock; setting it LOW clears Q1. |
| 2 | D1 | input | Data input for flip-flop 1, transferred to Q1 on the positive-going transition of CK1. |
| 3 | CK1 | input | Clock pulse input for flip-flop 1, positive-edge triggered. |
| 4 | PR1 | input | Active-low direct preset input for flip-flop 1, independent of the clock; setting it LOW presets Q1 HIGH. |
| 5 | Q1 | output | True output of flip-flop 1. |
| 6 | Q1_N | output | Complementary (inverted) output of flip-flop 1, shown as Q1 with overbar. |
| 7 | GND | power_in | Ground pin. |
| 8 | Q2_N | output | Complementary (inverted) output of flip-flop 2, shown as Q2 with overbar. |
| 9 | Q2 | output | True output of flip-flop 2. |
| 10 | PR2 | input | Active-low direct preset input for flip-flop 2, independent of the clock; setting it LOW presets Q2 HIGH. |
| 11 | CK2 | input | Clock pulse input for flip-flop 2, positive-edge triggered. |
| 12 | D2 | input | Data input for flip-flop 2, transferred to Q2 on the positive-going transition of CK2. |
| 13 | CLR2 | input | Active-low direct clear input for flip-flop 2, independent of the clock; setting it LOW clears Q2. |
| 14 | VCC | power_in | Supply voltage pin; recommended operating range 2.0V to 5.5V, absolute maximum 7.0V. |
