HT8051ARTZ

HTCSEMI · Comparators · SOT-23-5

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.
