MAX3221CDBE4

TEXAS INSTRUMENTS  MAX3221CDBE4  收发器, RS232, 3V-5.5电源, SSOP-16

The is a RS-232 Line Driver and Receiver with dedicated enable pin and a dual charge-pump circuit and ±15kV ESD protection pin to pin serial-port connection pins, including GND. The device meets the requirements of A/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 to 5.5V supply. This device operates at data signalling rate up to 250kbps and a maximum of 30V/µs driver output slew rate. Flexible control options for power management are available when the serial port is inactive. The automatic power-down feature functions when FORCEON is low and FORCEOFF is high. During this mode of operation, if the device does not sense a valid RS-232 signal on the receiver input, the driver output is disabled and the supply current is reduced to 1µA.
