DS26C32AMWG/883

Overview

The DS26C32AMWG/883 is a quad differential line receiver manufactured by Texas Instruments, designed to meet RS-422 and Federal Standards 1020 and 1030. It features a CMOS design for low power consumption with an input sensitivity of ±200 mV over a common mode voltage range of ±7 V. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. It includes TRI-STATE outputs with 6 mA source and sink capability and provides enable/disable functions for all four receivers.

Feature Summary

• CMOS architecture providing low power characteristics while maintaining high-speed performance
• Input fail-safe circuitry prevents output oscillation on unused channels
• TRI-STATE outputs allow direct connection to system buses without loading the line
• Inputs do not load the transmission line when the supply voltage (VCC) is 0 V

Applications

• Balanced digital data transmission systems compliant with RS-422 standards
• Unbalanced digital data transmission systems compliant with Federal Standards 1020 and 1030
• Two-wire balanced communication networks requiring high noise immunity

Procurement Notes

Verify that the component matches the specific military-grade qualification requirements associated with the /883 suffix. Confirm the package type corresponds to the Ceramic Flatpack (CFP) variant intended for surface mount or specialized through-hole applications. Ensure compatibility with existing Mil-Std-883 testing protocols if required for your specific deployment environment.

Selection Notes

Select this component when a quad differential receiver is needed for RS-422 interfaces requiring extended industrial temperature ranges. It serves as a pin-compatible alternative to the DS26LS32A and AM26LS32. Consider the TRI-STATE functionality for bus sharing applications and verify that the 5 V supply voltage aligns with your system's power distribution network.

Part Context

This part belongs to the DS26C32AMQML series of quad differential line receivers. It shares functional similarities with other RS-422 interface ICs but is distinguished by its specific ceramic packaging and radiation-hardened or high-reliability manufacturing processes indicated by the /883 designation. It is part of Texas Instruments' portfolio of robust interface solutions for demanding environments.

Replacement Considerations

The DS26C32AMWG/883 is pin-compatible with the DS26LS32A and AM26LS32. Verify electrical specifications and package dimensions before substitution to ensure mechanical fit and signal integrity in the target application.
