AM26LS33AMJB

Drivers, Receivers, Transceivers Overview

The AM26LS33AMJB is a quadruple differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It meets ANSI TIA/EIA-422-B and ITU V.10/V.11 standards. The device operates from a single 5-V supply (4.5 V to 5.5 V) with a maximum supply current of 70 mA. It features a ±15-V common-mode range and ±500-mV sensitivity. The package is a 16-pin CDIP (J). Electrical characteristics include a typical propagation delay of 35 ns and an input hysteresis of 50 mV. It supports operation over the full military temperature range of -55°C to 125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix JB corresponds to the 16-pin Ceramic Dual In-line Package (CDIP) variant. Confirm that the military temperature rating (-55°C to 125°C) aligns with your environmental requirements. Check the latest Package Option Addendum for current production status and lead finish specifications such as SNPB.

Drivers, Receivers, Transceivers Selection Notes

Select this component if your application requires robust performance in extreme temperatures or harsh environments. The AM26LS33A series offers improved sensitivity compared to previous generations due to an additional amplification stage. Ensure the system voltage remains within the 4.5 V to 5.5 V range for optimal operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the AM26LS32Ax and AM26LS33Ax family of quadruple differential line receivers. The 'AM' suffix indicates characterization for the full military temperature range. The 'JB' suffix specifically denotes the 16-pin CDIP package option. These devices are engineered for long-distance data transmission up to 1000 meters.

Drivers, Receivers, Transceivers Replacement Considerations

The AM26LS32AMJB serves as a functional alternative with different sensitivity specifications. Other variants like AM26LS33ACDR offer similar electrical functions but differ in package type and operating temperature range.
