MCP1402T-E from Microchip Tech, 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 | GND | power_in | Ground return pin that must have a low-impedance connection to the bias supply return, and which carries high peak currents when the capacitive load discharges. |
| 2 | VDD | power_in | Bias supply input rated 4.5 V to 18 V that must be decoupled to ground with a local capacitor to supply the peak driver current. |
| 3 | IN | input | High-impedance TTL/CMOS-compatible control input with hysteresis; the input range is -5 V to VDD + 0.3 V, and on the MCP1402 the output is non-inverting with respect to this input. |
| 4 | GND | power_in | Second ground pin, which the datasheet states must be connected together with pin 1 for the device to operate correctly. |
| 5 | OUT | output | CMOS push-pull output that withstands 0.5 A peak sink/source current at VDD = 18 V and 0.5 A latch-up reverse current. |
