XR33194ESBTR

MaxLinear · Pre-ordered Chips · TSOT-23-6

XR33194ESBTR from MaxLinear, in a TSOT-23-6. 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 DI input Driver input: a low forces Y low and Z high, a high forces Y high and Z low; input range -0.3V to 7.0V.
2 VCC power_in Power supply, 3.3V ±5% (3.135V to 3.465V), bypass with 0.1µF capacitor to ground.
3 DE input Driver output enable: high enables outputs Y and Z, low tri-states them and puts the device into low-power shutdown (2µA max); hot swap function is implemented on this pin.
4 Z output ±15kV HBM ESD protected RS-485/RS-422 inverting driver output, rated ±18V on the bus.
5 GND power_in Supply ground.
6 Y output ±15kV HBM ESD protected RS-485/RS-422 non-inverting driver output, rated ±18V on the bus.
