MAX3243EIPWG4

TEXAS INSTRUMENTS  MAX3243EIPWG4  收发器, RS232, 8驱动器, 3V-5.5电源, TSSOP-28

The is a RS-232 multichannel Line Driver/Receiver with ±15kV ESD HBM and IEC61000-4-2, air-gap discharge and ±8kV ESD IEC61000-4-2, contact discharge protection on serial-port connection pins. 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. This combination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT or compatible. The charge pump and four small external capacitors allow operation from a single 3 to 5.5V supply. In addition, the device includes an always-active non-inverting output ROUT2B, which allows applications using the ring indicator to transmit data while the device is powered down. The device operates at data signalling rates up to 250kB and a maximum of 30V/µs driver output slew rate. Flexible control options for power management are available when the serial port is inactive.
