SN75C3222 3V 至 5.5V 多通道 RS-232 兼容线路驱动器/接收器
The SN65C3222 and SN75C3222 consist 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 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. The 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.
The SN65C3222 and SN75C3222 can be placed in the power-down mode by setting PWRDOWN\ low, which draws only 1 µA from the power supply. When the devices are powered down, the receivers remain active while the drivers are placed in the high-impedance state
