**HTCSEMI** · Comparators · MSOP-8

HT8052ARMZ from HTCSEMI, in a MSOP-8. 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 A | output | Comparator A output, which swings rail to rail and is CMOS/TTL compatible according to the feature list. |
| 2 | -IN A | input | Inverting input of comparator A, with internal hysteresis (about 5 mV) to ensure clean switching. |
| 3 | +IN A | input | Non-inverting input of comparator A, which is DC coupled. |
| 4 | -VS | power_in | Negative supply rail of the comparator, the most negative supply for the device. |
| 5 | +IN B | input | Non-inverting input of comparator B, which is DC coupled. |
| 6 | -IN B | input | Inverting input of comparator B, with internal hysteresis (about 5 mV) to ensure clean switching. |
| 7 | OUT B | output | Comparator B output, which swings rail to rail and is CMOS/TTL compatible according to the feature list. |
| 8 | +VS | power_in | Positive supply pin; the recommended operating supply range is 2.7 V to 5.5 V. |
