The SP26LV431 is a quad differential line driver that meets the specifications of the EIA standard RS-422 serial protocol. The SP26LV431 features MaxLinearr'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 SP26LV431 features a driver enable control common to all four drivers that places the output pins in a high impedance state. Since the cabling can be as long as 4,000 feet, the RS-422 drivers of the SP26LV431 are equipped with a wide common-mode output voltage range to accommodate ground potential differences.
- Quad Differential Line Drivers
- Compatible with the EIA standard for RS-422 serial protocol
- High-Z Output Control
- At Least 60Mbps Transmission Rates
- 11ns Typical Driver Propagation Delays
- Less than 1ns Typical Output Skew
- Single +3.3V Supply Operation
- Common Driver Enable Control
- Compatibility with the industry standard 26LV31
- Ideal For Use with SP26LV431, Quad Receivers

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps) | Maximum RS-232 Cable Length (ft) |
19200 | 50 |
9600 | 500 |
4800 | 1000 |
2400 | 3000 |
Fail Safe is an attempt to keep the output of the RS-485 receiver to a known state. Transceivers may have standard fail safe or advanced / enhanced receiver fail safe features. Standard fail safe supports open inputs while enhanced fail safe transceivers such as the SP339 and XR34350 support open input, shorted input and undriven terminated lines without external biasing. See Application Note ANI-22 for more detail.
