# XR33180ESBTR

**MaxLinear** · Pre-ordered Chips · TSOT-23-5

XR33180ESBTR from MaxLinear, in a TSOT-23-5. 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 | VCC | power_in | Power supply input, to be bypassed with a 0.1μF capacitor; the VCC supply range is 3.0V to 5.5V. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | RO | output | Receiver output that is high when (VA-VB) ≥ -50mV and low when (VA-VB) ≤ -200mV. |
| 4 | B | input | RS-485/RS-422 inverting receiver input, ±15kV ESD protected. |
| 5 | A | input | RS-485/RS-422 non-inverting receiver input, ±15kV ESD protected. |
