# TLV7211AIDR

**Texas Instruments** · Comparators · SOIC-8

TLV7211AIDR from Texas Instruments, in a SOIC-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 | NC | unconnected | No internal connection. |
| 2 | IN- | input | Inverting comparator input with rail-to-rail input common-mode range extending beyond VCC- and VCC+, and absolute maximum input voltage of VCC- - 0.3 V to VCC+ + 0.3 V. |
| 3 | IN+ | input | Non-inverting comparator input with rail-to-rail input common-mode range extending beyond VCC- and VCC+, and absolute maximum input voltage of VCC- - 0.3 V to VCC+ + 0.3 V. |
| 4 | VCC- | power_in | Negative supply (GND in single-supply use); supply voltage VCC+ - VCC- must be 2.7 V to 15 V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Push-pull CMOS comparator output that drives capacitive loads directly without a pull-up resistor, held low during power-on reset, with output current rated ±30 mA absolute maximum. |
| 7 | VCC+ | power_in | Positive supply; supply voltage VCC+ - VCC- must be 2.7 V to 15 V (16 V absolute maximum). |
| 8 | NC | unconnected | No internal connection. |
