TLV1871DDFR from Texas Instruments, in a TSOT-23-8. 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 | VEEO | power_in | Output negative supply voltage; VEEO must be between VEEI and VEEI + 20V per absolute maximum ratings. |
| 2 | IN+ | input | Non-inverting input, rail-to-rail, diode-clamped to VEEI and VCCI with input current limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 3 | IN- | input | Inverting input, rail-to-rail, diode-clamped to VEEI and VCCI with input current limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 4 | VEEI | power_in | Input negative supply voltage; VCCI to VEEI input supply range is 2.7V to 40V. |
| 5 | NC | unconnected | No connect pin with no internal connection to the circuit. |
| 6 | VCCO | power_in | Output positive supply voltage, rated from VEEO - 0.3V to VCCI + 0.3V. |
| 7 | OUT | output | Push-pull comparator output referenced to VEEO and VCCO, diode-clamped to both, with output current internally limited to below 35mA. |
| 8 | VCCI | power_in | Input positive supply voltage; VCCI to VEEI input supply range is 2.7V to 40V with an absolute maximum of 42V. |
