Overview
SP331 Programmable Dual RS-232/RS-485 Transceiver Description The SP331 is a programmable RS-232 and/or RS-485 transceiver IC.
The SP331 contains four drivers and four receivers when selected in RS-232 mode; and two drivers and two receivers when selected in RS-485 mode.
The SP331 also contains a dual mode which has two RS-232 drivers/receivers plus one differential RS-485 driver/receiver.
The RS-232 transceivers can typically operate at 230kbps while adhering to the RS-232 specifications.
The RS-485 transceivers can operate up to 10Mbps while adhering to the RS-485 specifications.
The SP331 includes a self-test loopback mode where the driver outputs are internally configured to the receiver inputs.
This allows for easy diagnostic serial port testing without using an external loopback plug.
The RS-232 and RS-485 drivers can be disabled (High-Z output) by controlling a set of four select pins.
Typical Applications Circuit FEATURES ■■ +5V Only Operation ■■ Software Programmable...
