GN Semic · Comparators · SOP-8

GN393 from GN Semic, in a SOP-8. 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 OUT1 output Comparator 1 output. Open-collector NPN output (emitter tied to GND) capable of sinking up to 16mA; requires external pull-up resistor to Vcc or any allowed supply.
2 IN1- input Comparator 1 inverting input. High-impedance input; typical bias current 25nA. Input common-mode range 0V to Vcc−1.5V.
3 IN1+ input Comparator 1 non-inverting input. High-impedance input; typical bias current 25nA. Input common-mode range 0V to Vcc−1.5V.
4 GND power_in Ground / negative supply return. Connect to 0V in single-supply operation or to the negative rail (down to −18V) in dual-supply operation.
5 IN2+ input Comparator 2 non-inverting input. High-impedance input; typical bias current 25nA. Input common-mode range 0V to Vcc−1.5V.
6 IN2- input Comparator 2 inverting input. High-impedance input; typical bias current 25nA. Input common-mode range 0V to Vcc−1.5V.
7 OUT2 output Comparator 2 output. Open-collector NPN output (emitter tied to GND) capable of sinking up to 16mA; requires external pull-up resistor to Vcc or any allowed supply.
8 Vcc power_in Positive supply. Single-supply 2.0V-36V or dual-supply ±1.0V-±18V. Typical supply current 0.4mA (max 1.0mA) with RL=∞, independent of supply voltage.

Provenance

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

  • Datasheet: GN Semic datasheet (5 pp, sha256 d6713c7bc3915963, 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.
