GS8740-TR

Gainsil · Comparators · SOT-23-5

GS8740-TR from Gainsil, in a SOT-23-5. 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 OUT output Comparator output, rail-to-rail and CMOS/TTL-compatible.
2 VSS power_in Negative supply (ground in single-supply operation); supply range VDD to VSS is 2.7V to 5.5V, absolute maximum 7.5V.
3 IN+ input Non-inverting comparator input, rail-to-rail with common-mode range VSS-0.1V to VDD+0.1V.
4 IN- input Inverting comparator input, rail-to-rail with common-mode range VSS-0.1V to VDD+0.1V.
5 VDD power_in Positive supply, 2.7V to 5.5V, with a 0.1uF ceramic bypass capacitor placed close to the pin.
