CD40175BNSR

Texas Instruments · Flip Flops · SO-16

CD40175BNSR from Texas Instruments, in a SO-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 CLEAR input Active-low clear input common to all four flip-flops; a low level simultaneously resets all flip-flops (Q low, Q-bar high).
2 Q1 output True output of flip-flop 1, updated on the positive-going clock transition.
3 Q1̅ output Complementary output of flip-flop 1.
4 D1 input Independent data input of flip-flop 1.
5 D2 input Independent data input of flip-flop 2.
6 Q2̅ output Complementary output of flip-flop 2.
7 Q2 output True output of flip-flop 2, updated on the positive-going clock transition.
8 VSS power_in Ground reference (VSS = pin 8) for the supply voltage.
9 CLOCK input Clock input common to all flip-flops; data is transferred to the Q outputs on the positive-going clock transition.
10 Q3 output True output of flip-flop 3, updated on the positive-going clock transition.
11 Q3̅ output Complementary output of flip-flop 3.
12 D3 input Independent data input of flip-flop 3.
13 D4 input Independent data input of flip-flop 4.
14 Q4̅ output Complementary output of flip-flop 4.
15 Q4 output True output of flip-flop 4, updated on the positive-going clock transition.
16 VDD power_in Positive supply (VDD = pin 16); recommended supply range 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS.
