DESCRIPTION  
The SP33ꢀ is a programmable RS-232 and/or RS-485 transceiver IC. The SP33ꢀ 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 SP33ꢀ also contains a dual mode which has  
two RS-232 drivers/receivers plus one differential RS-485 driver/receiver.  
TheRS-232transceiverscantypicallyoperateat230kbpswhileadheringtotheRS-232speci-  
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.
