DS26LV31TM – NATIONAL SEMICONDUCTOR

Overview

The Texas Instruments DS26LV31TM is a robust quad differential line driver designed for RS-422 and RS-485 communication interfaces. Its primary function is to provide robust signal integrity for differential data transmission over extended distances, even in noisy environments. A critical design consideration for this device is the trade-off between its low power consumption (3V to 3.6V supply) and the potential for signal degradation at very high data rates, where slew rate limiting might become a factor in achieving maximum specified throughput without careful impedance matching and termination.
