SGM8740YN5G

SGMICRO · Comparators · SOT-23-5

SGM8740YN5G from SGMICRO, 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 uses a current-driven stage that pulls to within 200mV of either rail with 4mA output current, is CMOS/TTL compatible, and tolerates a continuous short-circuit to either rail.
2 -VS power_in Negative supply rail (GND in single-supply use); the device operates from 2.7V to 5.5V across +VS and -VS.
3 IN+ input Non-inverting comparator input with rail-to-rail range; it can be driven 0.1V beyond either supply rail without damage or false output inversion.
4 IN- input Inverting comparator input with rail-to-rail range; it can be driven 0.1V beyond either supply rail without damage or false output inversion.
5 +VS power_in Positive supply rail, specified from 2.7V to 5.5V (absolute maximum 6V from +VS to -VS).
