Data sheet:
Application note:
The MAX3222E consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15kV 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 3V to 5.5V supply. The device operates at typical data signaling rates up to 500kbit/s and a maximum of 30V/µs driver output slew rate.
The MAX3222E can be placed in the power-down mode by setting the power-down ( PWRDOWN) input low, which draws only 1µA from the power supply. When the device is powered down, the receivers remain active while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is disabled; V+ is lowered to VCC, and V– is raised toward GND. Receiver outputs also can be placed in the high-impedance state by setting enable ( EN) high.
- ESD Protection for RS-232 bus pins
- ±15kV Human-body model (HBM)
- ±8kV IEC61000-4-2, Contact discharge
- ±15kV IEC61000-4-2, Air-gap discharge
- Meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards
- Operates with 3V to 5.5V VCC supply
- Operates up to 500kbit/s
- Two drivers and two receivers
- Low standby current: 1µA typical
- External capacitors: 4 × 0.1µF
- Accepts 5V logic input with 3.3V supply
- Alternative high-speed pin-compatible device (1Mbit/s) for SNx5C3222E
