TLV7042QDGKRQ1 from Texas Instruments, in a VSSOP-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 | OUTA | output | Channel A output; open-drain on the TLV704x-Q1 variant, so it can be pulled up above VCC, with output voltage limited to VEE - 0.3 V to 7 V. |
| 2 | INA- | input | Inverting input of channel A; input terminals are diode-clamped to VEE, and signals that swing 0.3 V below VEE must be current-limited to 10 mA or less. |
| 3 | INA+ | input | Noninverting input of channel A; input voltage range is VEE - 0.1 V to VCC + 0.1 V. |
| 4 | VEE | power_in | Negative (lowest) supply or ground for single-supply operation; supply voltage VS = VCC - VEE is 1.6 V to 6.5 V recommended (7 V absolute maximum). |
| 5 | INB+ | input | Noninverting input of channel B; input voltage range is VEE - 0.1 V to VCC + 0.1 V. |
| 6 | INB- | input | Inverting input of channel B; input terminals are diode-clamped to VEE, and signals that swing 0.3 V below VEE must be current-limited to 10 mA or less. |
| 7 | OUTB | output | Channel B output; open-drain on the TLV704x-Q1 variant, so it can be pulled up above VCC, with output voltage limited to VEE - 0.3 V to 7 V. |
| 8 | VCC | power_in | Positive (highest) supply; supply voltage VS = VCC - VEE is 1.6 V to 6.5 V recommended (7 V absolute maximum). |
