DS96176CN

Overview

The DS96176CN is a monolithic RS-485/RS-422 differential bus transceiver manufactured by Texas Instruments. It integrates a TRI-STATE differential line driver and a receiver operating from a single 5.0V supply. The device supports bidirectional data communication on balanced multipoint buses, meeting EIA Standard RS-485 and RS-422A specifications. Key electrical parameters include a recommended supply voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to +70°C. The driver provides up to ±60mA output current capability with thermal shutdown protection at approximately 160°C junction temperature. The receiver features a typical input impedance of 15kΩ, sensitivity of ±200mV, and hysteresis of 50mV.

Feature Summary

• Supports bidirectional data communication on balanced multipoint transmission lines
• Features individual active-high enable controls for the driver and receiver sections
• Includes thermal shutdown protection and positive/negative current-limiting for fault tolerance
• Provides wide common mode voltage ranges suitable for noisy environments

Applications

• Multipoint transmission systems requiring RS-485 or RS-422 compliance
• Industrial control networks utilizing balanced bus architectures
• Communication interfaces compatible with quad differential drivers and receivers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and marking consistency against the SNLS393A datasheet specifications. Ensure storage conditions remain within specified limits to prevent degradation prior to assembly.

Selection Notes

Select this component for applications requiring standard RS-485/RS-422 performance in commercial temperature ranges. Consider the 8-lead DIP package constraints for PCB layout. Evaluate power dissipation requirements relative to the 930mW maximum rating at 25°C ambient temperature.

Part Context

Originally developed by National Semiconductor, this part was integrated into Texas Instruments' portfolio following their acquisition. The DS96176 series serves as a foundational interface solution for legacy industrial equipment still utilizing through-hole mounting technologies.

Replacement Considerations

Compatible alternatives include the SN75176ADRE4 and SN75176BDR. Verify pinout compatibility and electrical parameter alignment before substitution.
