DS96F174ME/883

Overview

The DS96F174ME/883 is a quad differential line driver designed to meet EIA-485 and EIA-422 standards. It utilizes L-FAST bipolar technology for high-speed operation up to 15 Mbps with reduced power consumption. The device features TRI-STATE outputs, thermal shutdown protection, and wide common mode output voltage range from -7.0V to +12.0V. It operates on a single +5.0V supply (4.50V to 5.50V) and supports an operating temperature range of -55°C to +125°C. The component is available in 16-lead CDIP and 20-lead LCCC ceramic packages.

Feature Summary

• Monotonic differential output switching ensures reliable signal transmission.
• Designed specifically for multipoint bus transmission applications.
• Includes positive and negative current-limiting protection against line faults.
• Features separate active high enables for each driver pair.

Applications

• Military and defense communication systems
• Multipoint data bus transmission networks
• Noisy industrial environments requiring wide common mode ranges

Procurement Notes

Verify the specific package variant required, as the DS96F174ME/883 designation corresponds to the 20-lead LCCC package. Confirm that the QML certification level meets the project's environmental and reliability requirements. Ensure proper handling procedures are followed due to limited built-in ESD protection during storage or installation.

Selection Notes

Select this component when independent enable control for each driver pair is necessary, distinguishing it from the DS96F172 which shares a common enable. Consider the 20-lead LCCC package if board space allows for larger ceramic footprints compared to the 16-lead CDIP option. Verify that the system requires the specific military-grade qualification associated with the /883 suffix.

Part Context

This part belongs to the DS96F17xMQML family of high-speed quad differential line drivers. It is functionally compatible with legacy parts such as the SN75174 and AM26LS31/MC3487 but offers improved performance through L-FAST bipolar technology. The family includes variants like the DS96F172MQML which differs primarily in its enable logic configuration.

Replacement Considerations

The SN75174 and AM26LS31 are listed as functionally compatible replacements. However, verify pinout compatibility and ensure that the replacement part meets the required MIL-STD-883 quality conformance inspection standards if used in qualified applications.

FAQ

How does the enable logic of the DS96F174 differ from the DS96F172?

The DS96F174 features separate active high Enables for each driver pair, whereas the DS96F172 uses a common active high and active low Enable for all four drivers.

What is the maximum data rate supported by this device?

The device is optimized for balanced multipoint data bus transmission at rates up to 15 Mbps.

Does the device provide protection against short circuits?

Yes, the device includes positive and negative current-limiting protection which protects the drivers from line fault conditions over a +12V to -7.0V common mode range.
