资 源 简 介
The MAX3222E 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 typical data signaling rates up to 500 kbit/s and a maximum of 30-V/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 1 µA from the power supply.
