Drivers

RS-232single channel3 V to 5.5 V250 kbit/sSSOP-16IEC ESD protection

MAX3221EIDBR is a 3 V to 5.5 V, single-channel RS-232 transceiver in a 16-pin SSOP package, intended for UART-to-RS-232 level conversion up to 250 kbit/s.

Best for

  • Low-power UART to RS-232 interfaces
  • 3.3 V or 5 V serial ports
  • Industrial and portable serial equipment

Avoid if

  • A data rate above 250 kbit/s is required
  • More than one RS-232 driver or receiver channel is required

Check before use

  • Verify the SSOP-16 DB land pattern.
  • Place charge-pump capacitors close to the device.
  • Review auto-power-down behavior for the connected serial equipment.
