AM26C31IDB

Drivers, Receivers, Transceivers Overview

The AM26C31IDB 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 an input capacitance of 6pF. It is housed in a 16-pin SSOP package and supports an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• BiCMOS circuitry reduces power consumption without sacrificing speed

• Common enable functions allow active-high or active-low configuration

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
• Military radars and sonars
• Avionics imaging systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature grade. Ensure that the selected variant matches the required thermal resistance and pinout specifications for the target PCB layout. Cross-reference the datasheet revision history to validate any recent changes to electrical characteristics or mechanical dimensions before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the AM26C31IDB when a quad differential driver compliant with RS-422 is required for noisy environments. Consider the SSOP package constraints regarding thermal dissipation and board space. Evaluate the need for automotive qualification if operating in harsh environments, as other variants like AM26C31Q exist. Ensure the system design accommodates the single 5V supply requirement and proper termination strategies for transmission lines.

Drivers, Receivers, Transceivers Part Context

The AM26C31 belongs to the AM26C31 family of quadruple differential line drivers produced by Texas Instruments. This series includes variants such as AM26C31C, AM26C31I, AM26C31Q, and AM26C31M, which differ primarily in their specified operating temperature ranges and reliability certifications. The IDB suffix specifically denotes the industrial temperature grade packaged in a small-outline shrink package.

Drivers, Receivers, Transceivers Replacement Considerations

The AM26C31 is documented as an improved replacement for the AM26LS31 device. Designers should verify pin compatibility and electrical parameter alignment when substituting legacy components.
