# TL712CPWR

**Texas Instruments** · Comparators · TSSOP-8

TL712CPWR from Texas Instruments, in a TSSOP-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 | Negative differential analog input; 4 kΩ nominal input impedance with 0 to 5.5 V common-mode range. |
| 3 | IN+ | input | Positive differential analog input; 4 kΩ nominal input impedance with 0 to 5.5 V common-mode range. |
| 4 | OE | input | Output enable input, active low; both outputs are in high-impedance state when OE is high. |
| 5 | GND | power_in | Ground, negative supply reference. |
| 6 | OUT+ | tri_state | Positive 3-state TTL output; high level 2.7 to 3.5 V, low level 0.4 to 0.5 V, can sink 16 mA. |
| 7 | OUT− | tri_state | Negative 3-state TTL output; high level 2.7 to 3.5 V, low level 0.4 to 0.5 V, can sink 16 mA. |
| 8 | VCC | power_in | Positive supply voltage input; 4.75 to 5.25 V operating range. |
