DS96F173MJ

Overview

The DS96F173MJ is a quad differential receiver manufactured by National Semiconductor, now part of Texas Instruments. It is designed for EIA-485 and EIA-422 communication standards. The device features a low-power CMOS process and operates with a supply voltage range typically from 3.0V to 5.5V. It provides four independent receivers with high noise immunity and fail-safe circuitry to ensure a high logic state when inputs are open. The component is available in a military-grade qualification variant, indicated by the 'MJ' suffix, suitable for harsh environments.

Feature Summary

• Supports EIA-485 and EIA-422 differential bus standards
• Includes fail-safe circuitry for open input protection
• High noise immunity for reliable data transmission
• Low power consumption via CMOS technology

Applications

• Industrial control systems requiring robust serial communication
• Military and aerospace avionics data buses
• Telecommunications equipment interfaces
• Harsh environment sensor networks

Procurement Notes

Verify the specific manufacturer source, as National Semiconductor was acquired by Texas Instruments. Confirm that the 'MJ' suffix denotes the correct military temperature range and package style required for your design. Ensure compatibility with existing board layouts and signal integrity requirements before finalizing procurement.

Selection Notes

Select this component when designing for EIA-485 or RS-422/423 applications requiring quad reception. The military grade (MJ) is essential for systems operating under extreme temperature conditions or strict reliability standards. Compare against standard commercial grades if environmental constraints allow for cost reduction.

Part Context

This component belongs to the DS96F17x family of interface devices. It serves as the receiving counterpart to drivers like the DS96F174. The family is widely used in legacy and current industrial designs where differential signaling is necessary for long-distance, noise-immune communication.

Replacement Considerations

Direct replacements include the DS96F173MQML for qualified military applications or the commercial DS96F173M/CN variants if environmental ratings permit. Verify pinout compatibility and electrical specifications before substitution.
