# MIC842LYC5-TR

**Microchip Tech** · Comparators · SC-70-5

MIC842LYC5-TR from Microchip Tech, in a SC-70-5. 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 | INP | input | Threshold input that monitors an external voltage; OUT asserts when VINP < VREF and releases when VINP > VREF + VHYST, and the input tolerates up to 6V regardless of supply. |
| 2 | GND | power_in | Ground. |
| 3 | NC | unconnected | No connect; not internally connected. |
| 4 | OUT | output | Active-high push-pull output (L version) that asserts high when VINP < VREF and remains high until VINP > (VREF + VHYST), with maximum output voltage of VDD. |
| 5 | VDD | power_in | Power supply input, operating range 1.5V to 5.5V. |
