SP33_00_0260
The SP33 is a programmable RS-232 and/or RS-485 transceiver IC. The SP33 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 SP33 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 speci-
fications. 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.
