HTCSEMI · Comparators · SOT-23-5
HT8051BRTZ from HTCSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +VIN | input | Non-inverting comparator input. Common-mode input range GND+0.2V to VDD-0.2V. Input resistance >100 GΩ; differential input capacitance 1.8pF. |
| 2 | GND | power_in | Ground return for the device. |
| 3 | -VIN | input | Inverting comparator input. Common-mode input range GND+0.2V to VDD-0.2V. Input resistance >100 GΩ; differential input capacitance 1.8pF. |
| 4 | OUTPUT | output | Rail-to-rail comparator digital output, CMOS/TTL compatible. VOH ≥ VDD-0.3V, VOL ≤ GND+0.3V. Short-circuit current to VDD ≈ 25mA. Rise/fall times 35/28ns. |
| 5 | VCC | power_in | Positive power supply, 2.7V to 5.5V (absolute max 5.5V). Quiescent current ~200uA. |
