DS3695N/NOPB

Overview

The DS3695N/NOPB is a multipoint RS-485/RS-422 transceiver manufactured by Texas Instruments. It operates on a single +5V supply and meets EIA standard RS-485 requirements with an extended common mode range of -7V to +12V. The device features TRI-STATE outputs, thermal shutdown protection, and high impedance to the bus when powered off. It supports up to 32 transceivers on the bus due to low combined driver/receiver impedance. Operating temperature ranges from 0°C to +70°C for commercial use. Package: PDIP-8.

Feature Summary

• Supports multipoint communication on RS-485 and RS-422 buses
• Includes thermal shutdown protection and high-impedance bus isolation
• Features TRI-STATE driver and receiver outputs

Applications

• Multipoint data transmission systems
• Industrial control networks
• Building automation systems

Procurement Notes

Verify the LIFEBUY status before procurement as this component is discontinued. Confirm that the PDIP-8 package aligns with existing PCB footprints. Ensure the 0°C to +70°C operating temperature range satisfies the environmental requirements of the target application.

Selection Notes

Select this part for applications requiring robust RS-485/RS-422 communication with extended common mode voltage tolerance. Consider the thermal shutdown feature for fault protection. Verify compatibility with the single +5V power supply requirement.

Part Context

This component belongs to the DS3695 family of multipoint transceivers. It is functionally related to the DS3695T (industrial temperature), DS3696, and DS3697 variants. The 'N' suffix indicates the PDIP package, while 'NOPB' signifies lead-free construction compliant with RoHS standards.

Replacement Considerations

DS3695TN/NOPB offers the same functionality in an industrial temperature range (-40°C to +85°C). Other compatible devices include the DS3696 and DS3697, which share similar electrical characteristics but may have different pin configurations or additional features.
