AM26C31IDR +BOM

Quadruple differential line driver

AM26C31IDR Information

Description

The Texas Instruments AM26C31IDR is a quad transmitter RS-422 device that meets or exceeds the requirements of TIA/EIA-422-B and ITU Recommendation V.11. It operates from a single 5V supply, has low power consumption (100µA typical), and high speed transmission (7ns typical). This device is designed for use in serial communications systems, industrial automation, motor control, and networking equipment. As a differential line driver and receiver, it provides robust signal transmission over long distances with high noise immunity. The AM26C31IDR is an improved replacement for the AM26LS31 device and is available in Q-Temp automotive qualification.

Features

According to the product information, the features of the AM26C31IDR are:

  • Meets or exceeds TIA/EIA-422-B and ITU Recommendation V.11 requirements
  • Low power consumption (Icc = 100 µA typical)
  • Operates from a single 5-V supply
  • High speed (tPLH = tPHL = 7 ns typical)
  • Low pulse distortion (tsk(p) = 0.5 ns typical)
  • High output impedance in power-off conditions
  • Improved replacement for AM26LS31 device
  • Available in Q-Temp automotive configuration with high-reliability features

These features make the AM26C31IDR suitable for serial communications systems, industrial automation, motor control, and networking equipment, serving as a differential line driver and receiver.

Package
