7.1 Overview

The AM26LS31xCN-E differential bus transmitter is a monolithic integrated circuit designed for unidirectional data communication on transmission lines. The device is designed for balanced transmission lines and meets ANSI Standard EIA/TIA-422B and ITU Recommendation V.11.

The AM26LS31xCN-E has a four 3-state differential line drivers that operate from a single 5V power supply. The driver also integrates active-high and active-low enables for precise device control.

The driver is designed to handle loads of a minimum of ±30mA of sink or source current. The driver features positive- and negative-current limiting for protection from line fault conditions.
