CD74AC174M96

Texas Instruments · Flip Flops · SOIC-16

CD74AC174M96 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 CLR input Active-low direct clear input: driving CLR low forces all Q outputs low regardless of CLK and D, and CLR must return high at least 1.5 ns before CLK rises (recovery time trec).
2 1Q output Output of flip-flop 1, which takes the value of 1D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
3 1D input Data input of flip-flop 1, which must be stable for the 2 ns setup time before the positive-going CLK edge.
4 2D input Data input of flip-flop 2, which must be stable for the 2 ns setup time before the positive-going CLK edge.
5 2Q output Output of flip-flop 2, which takes the value of 2D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
6 3D input Data input of flip-flop 3, which must be stable for the 2 ns setup time before the positive-going CLK edge.
7 3Q output Output of flip-flop 3, which takes the value of 3D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
8 GND power_in Ground pin.
9 CLK input Common clock input: D is transferred to Q on the positive-going CLK edge, and D has no effect at the output while CLK is high or low.
10 4Q output Output of flip-flop 4, which takes the value of 4D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
11 4D input Data input of flip-flop 4, which must be stable for the 2 ns setup time before the positive-going CLK edge.
12 5Q output Output of flip-flop 5, which takes the value of 5D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
13 5D input Data input of flip-flop 5, which must be stable for the 2 ns setup time before the positive-going CLK edge.
14 6D input Data input of flip-flop 6, which must be stable for the 2 ns setup time before the positive-going CLK edge.
15 6Q output Output of flip-flop 6, which takes the value of 6D on the positive CLK edge and holds its state while CLR is high and CLK is not rising.
16 VCC power_in Supply pin; the recommended supply range is 1.5 V to 5.5 V.
