SLLS408H – JANUARY 2000 – REVISED OCTOBER 2016 MAX3222 3-V to 5.5-V Multichannel RS-232 Line Driver and Receiver With ±15-kV ESD
Protection
1 Features 3 Description The MAX3222 consists of two line drivers, two line
receivers, and a dual charge-pump circuit with В±15-kV
ESD protection pin to pin (serial-port connection pins,
including GND). The device meets the requirements
of TIA/EIA-232-F and provides the electrical interface
between an asynchronous communication controller
and the serial-port connector. The charge pump and
four small external capacitors allow operation from a
single 3-V to 5.5-V supply. The device operates at
data signaling rates up to 250 kbit/s and a maximum
of 30-V/Ојs driver output slew rate. 1 RS-232 Bus-Pin ESD Protection Exceeds В±15 kV
Using Human-Body Model (HBM)
Meets or Exceeds the Requirements of
TIA/EIA-232-F and ITU v.28 Standards
Operates With 3-V to 5.5-V VCC Supply …
