SN74LS112AD

Texas Instruments · Flip Flops · SOIC-16

SN74LS112AD from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1CLK input Clock input of flip-flop 1, which transfers J/K data to the outputs on the negative-going edge.
2 1K input K data input of flip-flop 1.
3 1J input J data input of flip-flop 1.
4 1PRE input Active-low asynchronous preset of flip-flop 1, which sets 1Q high regardless of the other inputs.
5 1Q output True output of flip-flop 1.
6 1Q̅ output Complementary output of flip-flop 1.
7 2Q̅ output Complementary output of flip-flop 2.
8 GND power_in Ground; the reference for all voltage values.
9 2Q output True output of flip-flop 2.
10 2PRE input Active-low asynchronous preset of flip-flop 2, which sets 2Q high regardless of the other inputs.
11 2J input J data input of flip-flop 2.
12 2K input K data input of flip-flop 2.
13 2CLK input Clock input of flip-flop 2, which transfers J/K data to the outputs on the negative-going edge.
14 2CLR input Active-low asynchronous clear of flip-flop 2, which resets 2Q low regardless of the other inputs.
15 1CLR input Active-low asynchronous clear of flip-flop 1, which resets 1Q low regardless of the other inputs.
16 VCC power_in Supply voltage; absolute maximum 7 V with respect to ground.
