DS3486M

Overview

The DS3486M is a quad RS-422 and RS-423 line receiver manufactured by National Semiconductor. It integrates four independent receivers within a single package, designed for high-speed data transmission over balanced lines. The device operates with a supply voltage range of 4.75V to 5.25V. It features low input impedance to minimize reflections and provides high noise immunity. The output drivers are compatible with standard TTL and CMOS logic levels. The component supports data rates up to 10 Mbps for RS-422 applications. It is housed in a 20-pin plastic dual in-line package (DIP).

Feature Summary

• Integrates four independent differential receivers for multi-channel communication.
• Supports both RS-422 and RS-423 interface standards for flexible system design.
• Provides high noise immunity suitable for noisy industrial environments.

Applications

• Multi-drop communication networks requiring robust signal reception.
• Industrial control systems utilizing RS-422/RS-423 protocols.
• Data acquisition systems needing isolated local bus connections.

Part Context

The DS3486M belongs to the family of high-speed differential line receivers from National Semiconductor. It serves as a complementary component to transmitters like the DS3485, forming complete link segments for serial communication buses. This specific model focuses on the receiving end of the physical layer interface.

Replacement Considerations

Compatible substitutes include the DS3486, DS3695, and MAX1486. Verify pin compatibility and electrical specifications against the original datasheet before substitution. Ensure the replacement supports the required RS-422/RS-423 standards.
