GENERAL DESCRIPTION
The SP337E is a dual mode serial transceiver containing both RS-232 and RS-485/422 line drivers and receivers.
The RS-232 mode provides three drivers and five receivers to support all eight signals commonly used in the DB9 serial port connector (3TX/5RX).
In RS-485 mode the device features two independent high speed RS-485/422 transmit and receive channels (2TX/2RX).
The default RS-485 configuration is full-duplex, but half-duplex operation can be obtained by tying together the TX and RI pins, and the TXEN and RXEN signals.
The SP337E is pin compatible to Exar’s SP334.
