# SN65ELT23DR

**Texas Instruments** · Translators, Level Shifters · SOIC-8

SN65ELT23DR 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 | D0 | input | Non-inverted PECL differential data input D0, with the datasheet's internal 50-kΩ pull-down resistor; the TTL output stays low when the inputs are open or below 1.3 V. |
| 2 | D0 (complement) | input | Inverted PECL differential data input (complement of D0) that forms the differential pair with pin 1; the datasheet gives PECL VIH/VIL and VIHCMR limits for this input pair. |
| 3 | D1 | input | Non-inverted PECL differential data input D1, with the datasheet's internal 50-kΩ pull-down resistor; the TTL output stays low when the inputs are open or below 1.3 V. |
| 4 | D1 (complement) | input | Inverted PECL differential data input (complement of D1) that forms the differential pair with pin 3; the datasheet gives PECL VIH/VIL and VIHCMR limits for this input pair. |
| 5 | GND | power_in | Ground reference, 0 V, for the device. |
| 6 | Q1 | output | TTL output Q1 rated for 24 mA: VOL is 0.5 V max at IOL = 24 mA and VOH is 2.4 V min at IOH = -3.0 mA, with a 50 mA continuous output-current absolute maximum. |
| 7 | Q0 | output | TTL output Q0 rated for 24 mA: VOL is 0.5 V max at IOL = 24 mA and VOH is 2.4 V min at IOH = -3.0 mA, with a 50 mA continuous output-current absolute maximum. |
| 8 | VCC | power_in | Positive supply: 4.75 V to 5.25 V with GND = 0 V, with an absolute maximum of 6 V. |

## CAD (KiCad official)

- Symbol: `SN65ELT23DR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `sn65elt23dr-etched.step` / `sn65elt23dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sn65elt23dr.step` / `sn65elt23dr.glb` are the bare package body.
