Tokmas · Comparators · SOT-23-5

CSGM8743 from Tokmas, 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, CMOS/TTL-compatible with rail-to-rail swing (VOH = Vs - 0.166V typ, VOL = 132mV typ at 4mA, Vs = 5V).
2 VSS power_in Negative supply (ground) pin; absolute maximum supply VDD to VSS is 7.5V.
3 IN+ input Non-inverting analog input, rail-to-rail common-mode range of -0.1V to +5.6V at VS = 5.5V, absolute maximum VSS-0.5V to VDD+0.5V.
4 IN- input Inverting analog input, rail-to-rail common-mode range of -0.1V to +5.6V at VS = 5.5V, absolute maximum VSS-0.5V to VDD+0.5V.
5 VDD power_in Positive supply pin, operating range +2.7V to +5.5V, absolute maximum 7.5V above VSS.
