HT6541ARTZ

HTCSEMI · Comparators · SOT-23-5

HT6541ARTZ 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 Push-pull CMOS/TTL-compatible output that swings rail-to-rail and is capable of driving heavy DC or capacitive loads.
2 VSS power_in Negative power supply, equal to GND in the electrical specifications (VDD - VSS up to 7.0V absolute maximum).
3 VIN+ power_in Non-inverting comparator input; input voltage range is VSS - 0.3V to VDD + 0.3V.
4 VIN- power_in Inverting comparator input; input voltage range is VSS - 0.3V to VDD + 0.3V and input current must be limited to ±2 mA beyond that range.
5 VDD power_in Positive power supply, 1.6V to 5.5V single-supply operation.
