SN74HC175DR

Texas Instruments · Flip Flops · SOIC-16

SN74HC175DR 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 asynchronous direct clear input shared by all four flip-flops; when LOW, forces all Q outputs LOW and all Q̄ outputs HIGH regardless of CLK or D; setup time before CLK↑ ≥ 20 ns at VCC = 4.5 V.
2 1Q output Non-inverting output of flip-flop 1; captures the state of 1D on the positive-going edge of CLK; IOH = −4 mA at VCC = 4.5 V, tpd = 30 ns max at VCC = 4.5 V.
3 1Q_N output Complementary (inverting) output of flip-flop 1; always the logical inverse of 1Q; IOL = 4 mA at VCC = 4.5 V.
4 1D input Data input of flip-flop 1; state is transferred to 1Q on the positive-going CLK edge; setup time tsu = 20 ns min at VCC = 4.5 V, hold time th = 0 ns.
5 2D input Data input of flip-flop 2; state is transferred to 2Q on the positive-going CLK edge; setup time tsu = 20 ns min at VCC = 4.5 V, hold time th = 0 ns.
6 2Q_N output Complementary (inverting) output of flip-flop 2; always the logical inverse of 2Q; IOL = 4 mA at VCC = 4.5 V.
7 2Q output Non-inverting output of flip-flop 2; captures the state of 2D on the positive-going edge of CLK; IOH = −4 mA at VCC = 4.5 V, tpd = 30 ns max at VCC = 4.5 V.
8 GND power_in Ground reference; continuous current through GND pin limited to ±50 mA.
9 CLK input Common positive-edge-triggered clock input for all four flip-flops; minimum pulse width tw = 16 ns at VCC = 4.5 V; maximum clock frequency fmax = 25 MHz (SN74HC175) at VCC = 4.5 V.
10 3Q output Non-inverting output of flip-flop 3; captures the state of 3D on the positive-going edge of CLK; IOH = −4 mA at VCC = 4.5 V, tpd = 30 ns max at VCC = 4.5 V.
11 3Q_N output Complementary (inverting) output of flip-flop 3; always the logical inverse of 3Q; IOL = 4 mA at VCC = 4.5 V.
12 3D input Data input of flip-flop 3; state is transferred to 3Q on the positive-going CLK edge; setup time tsu = 20 ns min at VCC = 4.5 V, hold time th = 0 ns.
13 4D input Data input of flip-flop 4; state is transferred to 4Q on the positive-going CLK edge; setup time tsu = 20 ns min at VCC = 4.5 V, hold time th = 0 ns.
14 4Q_N output Complementary (inverting) output of flip-flop 4; always the logical inverse of 4Q; IOL = 4 mA at VCC = 4.5 V.
15 4Q output Non-inverting output of flip-flop 4; captures the state of 4D on the positive-going edge of CLK; IOH = −4 mA at VCC = 4.5 V, tpd = 30 ns max at VCC = 4.5 V.
16 VCC power_in Positive supply voltage; recommended operating range 2 V to 6 V; bypass with 0.1 µF capacitor placed as close to the pin as possible; ICC max = 80 µA at VCC = 6 V.
