74HC175D

Nexperia · Flip Flops · SOIC-16

74HC175D from Nexperia, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 MR input Asynchronous master reset input, active LOW. Driving MR LOW forces all four Q outputs LOW and all Q-bar outputs HIGH independently of the clock.
2 Q0 output True (non-inverting) flip-flop output for channel 0. Reflects the stored D0 value after a LOW-to-HIGH CP edge.
3 Q0_N output Complementary (inverted) flip-flop output for channel 0.
4 D0 input Data input for flip-flop 0. Sampled on the LOW-to-HIGH transition of CP subject to setup/hold timing.
5 D1 input Data input for flip-flop 1. Sampled on the LOW-to-HIGH transition of CP.
6 Q1_N output Complementary (inverted) flip-flop output for channel 1.
7 Q1 output True (non-inverting) flip-flop output for channel 1.
8 GND power_in Ground reference (0 V).
9 CP input Common clock input, positive-edge triggered. All four flip-flops latch their D inputs on the LOW-to-HIGH transition.
10 Q2 output True (non-inverting) flip-flop output for channel 2.
11 Q2_N output Complementary (inverted) flip-flop output for channel 2.
12 D2 input Data input for flip-flop 2. Sampled on the LOW-to-HIGH transition of CP.
13 D3 input Data input for flip-flop 3. Sampled on the LOW-to-HIGH transition of CP.
14 Q3_N output Complementary (inverted) flip-flop output for channel 3.
15 Q3 output True (non-inverting) flip-flop output for channel 3.
16 VCC power_in Positive supply voltage. 2.0 V to 6.0 V for 74HC175; 4.5 V to 5.5 V for 74HCT175.
