# SN65CML100DR

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

SN65CML100DR 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-connect pin with no internal connection; the datasheet lists it only as NC in the pin assignments and pin descriptions. |
| 2 | A | input | Non-inverting differential receiver input, compatible with LVDS, LVPECL and CML levels, with a 0 V to 4 V input voltage range and a differential input magnitude |VID| of 0.1 V to 1 V. |
| 3 | B | input | Inverting differential receiver input, compatible with LVDS, LVPECL and CML levels, with a 0 V to 4 V input voltage range and a differential input magnitude |VID| of 0.1 V to 1 V. |
| 4 | VBB | power_out | Internally generated reference voltage output for single-ended LVPECL input; when used it must be decoupled with a 0.01-µF capacitor, sourcing or sinking must be limited to 400 µA, and it should be left open when not used. |
| 5 | GND | power_in | Ground reference for the device, to which all voltages are referenced (network ground). |
| 6 | Z | output | Differential CML driver output (inverted polarity with respect to Y), intended to drive 50-Ω or 25-Ω loads terminated to VTT. |
| 7 | Y | output | Differential CML driver output, intended to drive 50-Ω or 25-Ω loads terminated to VTT. |
| 8 | VCC | power_in | Positive supply, rated 3 V to 3.6 V (3.3 V nominal) with an absolute maximum of 4 V. |
