DS26C32AMJ/883

Overview

The DS26C32AMJ/883 is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It meets RS-422, RS-423, Federal Standard 1020, and 1030 standards. The device features a CMOS design with an input sensitivity of ±200 mV over a common mode voltage range of ±7 V. It includes TRI-STATE outputs with 6 mA source and sink capability and provides a common enable/disable function for all four receivers. Operating conditions include a supply voltage (VCC) range of 4.5 V to 5.5 V and an operating temperature range from -55°C to +125°C.

Feature Summary

• CMOS architecture providing low power consumption while maintaining high performance
• Internal pull-up and pull-down resistors prevent output oscillation on unused channels
• Inputs do not load the line when VCC is 0 V
• TRI-STATE outputs facilitate connection to system buses

Applications

• Balanced digital data transmission systems
• Unbalanced digital data transmission systems
• RS-422 compliant communication interfaces
• Federal Standard 1020 and 1030 applications

Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the package type and material specifications. Ensure that the component status matches current production requirements. Confirm compliance with Mil-Std-883 Group A quality conformance inspection levels if required for the application environment.

Selection Notes

Select this component for applications requiring robust differential reception under extreme environmental conditions. The wide common mode voltage range supports diverse signal environments. Verify compatibility with existing bus architectures due to the TRI-STATE output configuration. Consider the CDIP package constraints for thermal management and physical integration in the target design.

Part Context

This part belongs to the DS26C32AMQML family of quad differential line receivers. It is pin-compatible with the DS26LS32A and AM26LS32 devices. The component is designed to replace older National Semiconductor equivalents while adhering to strict military-grade reliability standards specified by the /883 suffix.

Replacement Considerations

The DS26LS32A and AM26LS32 are confirmed pin-compatible replacements within the same functional category.
