HT8051ARTZ from HTCSEMI, 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: pulled to VDD when high and to GND when low, with rail-to-rail CMOS/TTL-compatible swing. |
| 2 | GND | power_in | Ground pin, to be connected to the most negative supply; all GND pads are connected on die. |
| 3 | VINP | input | DC-coupled input pad, labelled as a video signal input in the pad table. |
| 4 | VINN | input | DC reference voltage input pad. |
| 5 | VDD | power_in | Positive power supply pin; the recommended operating range is 2.7 V to 5.5 V per Table 2, although the pad table labels it 3.3 V/5 V. |
