GS8747-TR

Gainsil · Comparators · SOT-23-5

GS8747-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 or ground; VDD to VSS operating range is 2.7V to 5.5V.
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 Rail-to-rail CMOS/TTL-compatible comparator output with 35.4mA typical short-circuit source current and 36.3mA typical sink current at VS=5V.
5 VDD power_in Positive supply, 2.7V to 5.5V (absolute maximum 7.5V above VSS); bypass with a 0.1uF ceramic capacitor close to the pin.
