Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +IN A | input | Noninverting input for channel A; the input common-mode range extends from VEE - 0.1 V to VCC + 0.1 V. |
| 2 | VCC | power_in | Positive (highest) supply; VS = VCC - VEE must be within 1.6 V to 6.5 V (1.2 V minimum for the S and L options), with an absolute maximum of 7 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | +IN B | input | Noninverting input for channel B; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less. |
| 5 | -IN B | input | Inverting input for channel B; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V. |
| 6 | OUT B | output | Open-drain output for channel B (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V. |
| 7 | OUT C | output | Open-drain output for channel C (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V. |
| 8 | -IN C | input | Inverting input for channel C; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V. |
| 9 | +IN C | input | Noninverting input for channel C; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less. |
| 10 | NC | unconnected | No internal connection. |
| 11 | VEE | power_in | Negative (lowest) supply or ground for single-supply operation. |
| 12 | +IN D | input | Noninverting input for channel D; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less. |
| 13 | -IN D | input | Inverting input for channel D; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V. |
| 14 | OUT D | output | Open-drain output for channel D (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V. |
| 15 | OUT A | output | Open-drain output for channel A (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V. |
| 16 | -IN A | input | Inverting input for channel A; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
