GS8749-TR

Gainsil · Comparators · SOT-23-5

GS8749-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 IN+ input Non-inverting comparator input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V (absolute maximum VSS-0.5V to VDD+0.5V).
2 VSS power_in Negative supply pin, ground in single-supply operation.
3 IN- input Inverting comparator input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V (absolute maximum VSS-0.5V to VDD+0.5V).
4 OUT output Open-drain, CMOS/TTL-compatible comparator output that requires an external pull-up resistor (RUP).
5 VDD power_in Positive supply pin, 2.7V to 5.5V operation (7.5V absolute maximum), with a 0.1uF ceramic bypass capacitor placed close to it.
