Description
JK flip flops can be designed by manually using simple gates but to avoid circuit complexity the 74LS76 gives the advantages to use two JK flip flops at the same time. The JK flip flop in this 7476 IC also has a preset and clear function which allows the IC to bypass the clock and inputs and give the different outputs. 7476 is TTL based and can be operated with any TTL based device or any microcontroller. The IC comes in multiple packages that make the IC use any hardware according to the requirement. The multiple IC can be used to make further ICs in case of necessary.
Pin Description of 74LS76:
| Pin Number | Pin Name | Description |
| 5 | Vcc | Powers the IC typically with 5V |
| 13 | Ground | Connected to the ground of the system |
| JK Flip Flop – 1 / JK Flip Flop – 2 | ||
| 1,6 | Clock-1/ Clock-2 | These pins must be provided with clock pulse for the flip flop |
| 2,7 | Preset-1 / Preset-2 | Preset input pin drives Flip Flop to a set state. |
| 16, 12 | 1K/ 2K | Input pin of the Flip Flop |
| 4,9 | 1J / 2J | Another Input pin of the Flip Flop |
| 14, 10 | 1Q(bar) / 2Q (bar) | Inverted output pin of Flip Flop |
| 15,11 | 1Q / 2Q | Output Pin of the Flip Flop |
| 3,8 | 1 CLR (bar)/ 2 CLR (bar) | Clear input pin drives Flip Flop to a reset state. |
