资 源 简 介

The SN65C3221 and SN75C3221 consist of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV ESD protecTIon pin to pin (serial-port connecTIon pins, including GND). These devices provide 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. These devices operate at data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/µs to 150 V/µs. Flexible control options for power management are available when the serial port is inactive. The auto-powerdown feature functions when FORCEON is low and FORCEOFF is high.
