SP431DS/08 SP431 High Speed, +3.3V Quad RS-422 Differential Line Driver © Copyright 1997 Sipex Corporation High Speed, +3.3V Quad RS-422 Differential Line Driver The SP431 is a quad differential line driver that meets the specifications of the EIA standard RS-422 serial protocol. The SP431 features Sipex's BiCMOS process allowing low power operational characteristics of CMOS technology while meeting all of the demands of the RS-422 serial protocol over 60Mbps under load. The RS-422 protocol allows up to 10 receivers to be connected to a multipoint bus transmission line. The SP431 features a driver enable control common to all four drivers and a tri-state output. Since the cabling can be as long as 4,000 feet, the RS-422 drivers of the SP431 are equipped with a wide common-mode output voltage range to accomodate ground potential differences. I Compatible with the EIA standard for RS-422 serial protocol I Quad Differential Line Drivers I Tri-state Output Control I At Least 60Mbps Transmission Rates I 6.0ns Typical Driver Propagation Delays I Less than 1ns Typical Output Skew I Single +3.3V Supply Operation I Common Driver Enable Control I Compatibility with the industry standard 26LV31

NOTE 2: Measured per input. All other inputs at VCC or GND. NOTE 3: This is the current sourced when a high output is shorted to GND. Only one output at a time should be shorted. Unless otherwise noted, the following specifications apply for VCC = +3.0V to +3.6V with Tamb = 25°C and all MIN and MAX limits apply across the recommended operating temperature range.

SP431DS/08 SP431 High Speed, +3.3V Quad RS-422 Differential Line Driver © Copyright 1997 Sipex Corporation SPECIFICATIONS (continued) NOTE 4: Skew is defined as the difference in propagation delays between complementary outputs at the 50% input. NOTE 5: Output disable time is the delay from ENABLE or ENABLE being switched to the output transistors turning off. The actual disable times are less than indicated due to the delay added by the RC time constant of the load. NOTE 6: CPD determines the no load dynamic power consumption, PD = (CPDVCC 2 f) + (ICCVCC), and the no load dynamic current consumption, IS = (CPDVCCf) + ICC. Unless otherwise noted, the following specifications apply for VCC = +3.0V to +3.6V, Tamb = 25°C, tr < 6ns, tf < 6ns, and all MIN and MAX limits apply across the recommended operating temperature range.
