3-V Supply • Alternative High-Speed Pin-Compatible Device (1 Mbps) – SNx5C3222 2 Applications • Battery-Powered Systems • PDAs • Notebooks • Laptops • Palmtop PCs • Hand-held Equipment 3 Description The MAX3222 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±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/μs driver output slew rate.
The MAX3222 can be placed in the power-down mode by setting PWRDOWN low, which draws only 1 μA from the power supply.
When the device is powered down, the receivers remain active while the drivers are placed in the high-impedance state.
Receiver outputs also can be placed in the highimpedance state by setting EN high.
