DS36F95M/NOPB

Overview

The DS36F95M/NOPB is a monolithic integrated circuit differential bus transceiver designed for bidirectional data communication on balanced multipoint transmission lines. It complies with EIA-485 and EIA-422A standards and utilizes L-FAST bipolar technology to achieve higher speeds and lower power consumption. The device integrates a TRI-STATE differential line driver and a differential input receiver operating from a single 5.0V supply. Key electrical parameters include a maximum data rate of 10 Mb/s, an operating temperature range of 0°C to +70°C, and a supply voltage range of 4.75V to 5.25V. It features thermal shutdown protection, current limiting, and high impedance inputs.

Feature Summary

• Complies with EIA-485 and EIA-422A standards
• Features thermal shutdown and current-limiting protection
• Operates from a single 5.0V power supply
• High impedance receiver input with typical hysteresis

Applications

• Multipoint transmission systems
• SCSI-1 (5 MHz) specification applications
• Noisy industrial environments requiring wide common mode ranges

Procurement Notes

Verify the component origin carefully as the datasheet originates from National Semiconductor, which was acquired by Texas Instruments. Confirm that the specific ordering suffix corresponds to the commercial grade specifications provided in the documentation. Ensure the package type matches the required board layout constraints.

Selection Notes

Select this component when EIA-485 or EIA-422A compliance is required for half-duplex communication. It serves as a pin-compatible alternative to the SN75176A and DS3695. Consider the commercial temperature range limits and ensure the system design accommodates the specified propagation delays and output drive capabilities.

Part Context

This part belongs to the DS16F95/DS36F95 family of differential bus transceivers. The 'DS36' prefix indicates the commercial temperature variant, while the 'M' suffix denotes the SOIC-8 package. These devices are engineered for robust performance in multipoint networks using L-FAST technology.

Replacement Considerations

Pin-compatible replacements include the SN75176A and the DS3695. Verify that any substitute maintains the same EIA-485/EIA-422A compliance and electrical characteristics within the required operating temperature range.
