DS3698N

Overview

The DS3698N is a multipoint RS-485 and RS-422 transceiver manufactured by National Semiconductor. It integrates both transmitter and receiver functions within a single package, supporting bidirectional data communication over differential lines. The device operates within a standard industrial temperature range of 0°C to 70°C and utilizes a 16-pin PDIP plastic package. As part of the DS369x series, it provides robust signal integrity for multi-drop bus configurations commonly found in industrial automation and building control networks.

Feature Summary

• Supports multipoint communication architectures compatible with RS-485 and RS-422 standards
• Integrates full-duplex or half-duplex transmission and reception capabilities on a single chip
• Designed for reliable data transfer in electrically noisy industrial environments

Applications

• Industrial automation control systems
• Building management and security networks
• Multi-drop sensor interfaces

Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired National Semiconductor. Confirm whether the specific unit is an original National Semiconductor product or a TI continuation. Check for lead-free compliance markings if environmental regulations apply to the deployment environment.

Selection Notes

Select this component when designing systems requiring long-distance, noise-immune serial communication across multiple nodes. Ensure the system voltage levels match the device specifications. Consider thermal dissipation requirements if operating at the upper limit of the specified temperature range.

Part Context

This component belongs to the DS369x family of line drivers and receivers. It shares functional similarities with parts like the DS3695 and DS3696 but may differ in specific electrical characteristics or pinout configurations. It serves as a foundational interface element for legacy and modern serial bus implementations.

Replacement Considerations

The DS3695N and DS3696N are related multipoint transceivers from the same family. Verify pin compatibility and specific electrical tolerances before substituting these alternatives.
