MCP6542-I

Microchip Tech · Comparators · SOIC-8

MCP6542-I from Microchip Tech, in a SOIC-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 digital output is CMOS/TTL-compatible push-pull and is capable of driving heavy DC or capacitive loads.
2 VINA- input Comparator A inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V.
3 VINA+ input Comparator A non-inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V.
4 VSS power_in Negative power supply pin, connected to ground in single-supply operation, with VDD rated 1.6V to 5.5V above it.
5 VINB+ input Comparator B non-inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V.
6 VINB- input Comparator B inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V.
7 OUTB output Comparator B digital output is CMOS/TTL-compatible push-pull and is capable of driving heavy DC or capacitive loads.
8 VDD power_in Positive power supply pin rated 1.6V to 5.5V, requiring a local bypass capacitor of 0.01 µF to 0.1 µF within 2 mm of the pin.

CAD (KiCad official)

  • Symbol: MCP6542-I
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mcp6542-i-etched.step / mcp6542-i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp6542-i.step / mcp6542-i.glb are the bare package body.
