Texas Instruments · Flip Flops · SOIC-16

CD74HCT109M96 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 1R input Active-low asynchronous reset for flip-flop 1; a low forces 1Q low and 1Q̄ high independently of the clock.
2 1J input J (set-side data) input of flip-flop 1, sampled on the positive edge of 1CP.
3 1K input K (reset-side data) input of flip-flop 1, sampled on the positive edge of 1CP.
4 1CP input Positive-edge clock input of flip-flop 1 with Schmitt-trigger input; the flip-flop changes state on the low-to-high transition.
5 1S input Active-low asynchronous set for flip-flop 1; a low forces 1Q high and 1Q̄ low independently of the clock.
6 1Q output True output of flip-flop 1.
7 1Q̄ output Complementary output of flip-flop 1.
8 GND power_in Ground reference for the device.
9 2Q̄ output Complementary output of flip-flop 2.
10 2Q output True output of flip-flop 2.
11 2S input Active-low asynchronous set for flip-flop 2; a low forces 2Q high and 2Q̄ low independently of the clock.
12 2CP input Positive-edge clock input of flip-flop 2 with Schmitt-trigger input; the flip-flop changes state on the low-to-high transition.
13 2K input K (reset-side data) input of flip-flop 2, sampled on the positive edge of 2CP.
14 2J input J (set-side data) input of flip-flop 2, sampled on the positive edge of 2CP.
15 2R input Active-low asynchronous reset for flip-flop 2; a low forces 2Q low and 2Q̄ high independently of the clock.
16 VCC power_in Supply pin; HCT types operate from 4.5 V to 5.5 V per the operating conditions.
