AM26C31INS

Drivers, Receivers, Transceivers Overview

The AM26C31INS is a quadruple differential line driver manufactured by Texas Instruments, designed to meet TIA/EIA-422-B and ITU V.11 standards. It operates from a single 5V supply (4.5V to 5.5V) with a typical quiescent current of 100μA. The device features four drivers with complementary outputs, providing high-current capability for balanced lines. Key electrical parameters include a propagation delay of 7ns typical, pulse skew of 0.5ns typical, and output currents of ±20mA. It is characterized for industrial temperature ranges (-40°C to +85°C) and housed in a SOIC-16 package.

Drivers, Receivers, Transceivers Feature Summary

• Complementary outputs provide high-current driving capability for twisted-pair or parallel-wire transmission lines.
• High-impedance state is maintained in power-off conditions to prevent bus contention.
• Configurable enable functions allow selection between active-high (G) or active-low (G) logic inputs.

Drivers, Receivers, Transceivers Applications

• Chemical and gas sensors
• Field transmitters including temperature and pressure sensors
• Motor control systems for brushless DC and brushed DC motors

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'INS' against the manufacturer's official ordering information to confirm the exact package type, temperature grade, and packaging configuration. Ensure the component meets the required environmental compliance standards such as RoHS for the intended deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-422 compliant interfaces requiring multiple differential drivers on a single chip. Consider the SOIC-16 package constraints and thermal resistance values if operating near maximum temperature limits. Verify that the 5V supply voltage aligns with the host controller logic levels.

Drivers, Receivers, Transceivers Part Context

Drivers, Receivers, Transceivers FAQ

How are the enable inputs configured?

The device provides both active-high (G) and active-low (G) enable inputs, allowing configuration to match the logic of the receiving or transmitting controller.

What is the behavior of the outputs during power-off?

The drivers enter a high-impedance state when the power supply is off, preventing interference with other devices on the bus.

Does the device support shutdown mode?

No, the AM26C31 does not feature a dedicated shutdown pin; it relies on the enable inputs to control output states.
