MAX3181EUK+T

Maxim Integrated · Pre-ordered Chips · SOT-23-5

MAX3181EUK+T from Maxim Integrated, in a SOT-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 INVALID output Output of the valid input detector; goes low if no valid RS-232 level appears on RIN for 30µs (typ) and high when a valid level is applied, with VOL max 0.4V at 1.6mA sink.
2 GND power_in Ground.
3 ROUT output Inverting receiver output (MAX3181E) with CMOS/TTL levels, VOL max 0.4V at 1.6mA sink.
4 RIN input RS-232 receiver input with ±25V input voltage range, 3kΩ to 7kΩ input resistance and ±15kV ESD protection (HBM).
5 VCC power_in Supply voltage, +3.0V to +5.5V; bypass with a 0.1µF capacitor close to the IC.
