GN74D

GN Semic · Flip Flops · SOIC-14

GN74D from GN Semic, in a SOIC-14. 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 1RD input Flip-flop 1 asynchronous reset (clear) input, active low. Forces 1Q low when asserted.
2 1D input Flip-flop 1 data input. Sampled on the rising edge of 1CP.
3 1CP input Flip-flop 1 clock input. Data on 1D is transferred to 1Q on the rising edge.
4 1SD input Flip-flop 1 asynchronous set (preset) input, active low. Forces 1Q high when asserted.
5 1Q output Flip-flop 1 main channel output. Follows 1D after the rising clock edge.
6 1Q_N output Flip-flop 1 complementary output. Inverse of 1Q.
7 GND power_in System ground reference (0 V).
8 2Q_N output Flip-flop 2 complementary output. Inverse of 2Q.
9 2Q output Flip-flop 2 main channel output. Follows 2D after the rising clock edge.
10 2SD input Flip-flop 2 asynchronous set (preset) input, active low. Forces 2Q high when asserted.
11 2CP input Flip-flop 2 clock input. Data on 2D is transferred to 2Q on the rising edge.
12 2D input Flip-flop 2 data input. Sampled on the rising edge of 2CP.
13 2RD input Flip-flop 2 asynchronous reset (clear) input, active low. Forces 2Q low when asserted.
14 VCC power_in Positive supply voltage, 2.0 V to 6.0 V operating range.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: GN Semic datasheet (11 pp, sha256 00531e44db35b40a, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
