SP337E - 3.3V TO 5V RS-232/RS-485/RS-422 MULTIPROTOCOL TRANSCEIVER

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).

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 MaxLinear’s SP334. The SP337EB features a maximum data rate of 250kbps in RS-232 mode and a maximum data rat e of 15Mbps in RS-485. However, the SP337EU features a maximum data rate of 1Mbps in RS-232 mode and a maximum data rate.
