DS26LS31CM/NOPB – NATIONAL SEMICONDUCTOR

Overview

The Texas Instruments DS26LS31CM/NOPB is a robust quad differential line driver designed for robust serial data transmission in noisy environments. Its primary function is to convert single-ended logic signals into differential voltage outputs, enabling reliable communication over extended distances. A critical design consideration for this device is managing the trade-off between slew rate control for EMI reduction and achieving maximum data throughput; aggressive slew rate limiting, while beneficial for signal integrity, can cap the achievable data rates in high-speed applications. This makes careful impedance matching and termination crucial for optimal performance.
