SP336EEY-L

The SP336EEY-L is a monolithic serial Multi Transceiver that contains both RS-232 and RS-485/RS-422 line drivers and receivers. The configuration of the SP336E can be reconfigured into eight operating modes including RS-232 only, RS-485/RS-422 only full or half duplex, two RS- 232/RS-485 mixed modes, two shutdown modes and a diagnostic loop-back mode. Modes may be selected at any time by changing the logic state of the three MODE pins. The device can implement a dual-mode serial port, mixed mode ports or as an interface signal translator. The Exar charge pumps deliver true RS-232 driver output voltages from a single power supply at either 3.3 or 5V. The SP336E requires only four 0.1µF capacitors for charge pump. A slew rate control pin configures driver outputs for either high data rate or slew-controlled data rates. Slew-controlled outputs minimize problems with reflections and ringing on long or un-terminated cables.
