TL331QDBVRQ1 from Texas Instruments, 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 | IN- | input | Inverting comparator input. Common-mode range extends from GND up to VCC - 1.5 V (25 °C). Must not go below GND by more than 0.3 V; can be driven up to 30 V with either input without damage. |
| 2 | VCC-/GND | power_in | Negative supply / ground reference. For single-supply operation this is tied to GND (0 V). For dual-supply operation, this is the negative rail; supply differential (VCC to VCC-/GND) must be 2 V to 36 V. |
| 3 | IN+ | input | Non-inverting comparator input. Common-mode range extends from GND up to VCC - 1.5 V (25 °C). Must not go below GND by more than 0.3 V; can be driven up to 30 V with either input without damage. |
| 4 | OUT | output | Open-collector comparator output. Requires an external pull-up resistor; can be wired-AND with other open-collector outputs. VOH withstands up to 30 V (IOH ≤ 1 µA over temp); VOL typ 150 mV @ IOL = 4 mA. IO absolute max 20 mA. |
| 5 | VCC | power_in | Positive supply. Single supply 2 V to 36 V (or 2 V to 36 V between VCC and VCC-/GND for dual-supply operation). Supply current 0.4 mA typ, 0.7 mA max at VCC = 5 V. |
