MCP6542T-E

Microchip Tech · Comparators · MSOP-8

MCP6542T-E from Microchip Tech, in a MSOP-8. 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 OUTA output Comparator A push-pull CMOS/TTL-compatible digital output, able to drive heavy DC or capacitive loads.
2 VINA- input Comparator A inverting input, a high-impedance CMOS input with low bias current.
3 VINA+ input Comparator A non-inverting input, a high-impedance CMOS input with low bias current.
4 VSS power_in Negative power supply, connected to ground in single-supply use and kept below VDD.
5 VINB+ input Comparator B non-inverting input, a high-impedance CMOS input with low bias current.
6 VINB- input Comparator B inverting input, a high-impedance CMOS input with low bias current.
7 OUTB output Comparator B push-pull CMOS/TTL-compatible digital output, able to drive heavy DC or capacitive loads.
8 VDD power_in Positive power supply, 1.6V to 5.5V above VSS, with a 0.01 µF to 0.1 µF bypass capacitor within 2 mm of the pin.
