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.
