SN65LVEL11DR 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 | Q0 | output | True PECL/ECL output of channel 0 of the 1:2 fanout buffer. |
| 2 | Q0̅ | output | Complementary PECL/ECL output of channel 0 of the 1:2 fanout buffer. |
| 3 | Q1 | output | True PECL/ECL output of channel 1 of the 1:2 fanout buffer. |
| 4 | Q1̅ | output | Complementary PECL/ECL output of channel 1 of the 1:2 fanout buffer. |
| 5 | VEE | power_in | Negative supply; 0 V in PECL mode, or -3.0 V to -3.8 V in NECL mode. |
| 6 | D̅ | input | Complementary PECL/ECL data input with a built-in 75 kΩ internal pull-down resistor. |
| 7 | D | input | True PECL/ECL data input with a built-in 75 kΩ internal pull-down resistor. |
| 8 | VCC | power_in | Positive supply; 3.0 V to 3.8 V in PECL mode, or 0 V in NECL mode. |
