DS3486MX

Overview

The DS3486MX/NOPB is a quad RS-422 and RS-423 line receiver manufactured by Texas Instruments. It features four independent receivers with TRI-STATE outputs that are compatible with 74LS logic standards. The device operates on a single 5V supply, with a voltage range of 4.75V to 5.25V. It supports data rates up to 10Mb/s and includes internal hysteresis for improved noise margins. Typical propagation delays are 19ns, with maximum switching times reaching 35ns. The component is housed in a 16-pin SOIC package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Four independent differential-input line receivers compliant with EIA RS-422 and RS-423 standards
• TRI-STATE output structures providing high-impedance states when the control pin is at a low logic level
• Internal hysteresis circuitry designed to improve noise margin and prevent output instability
• TTL-compatible outputs buffered by PNP devices to minimize loading effects

Applications

• Balanced/unbalanced voltage digital interface circuits
• High-speed serial communication systems requiring differential signaling
• Industrial equipment utilizing RS-422 or RS-423 protocols

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability status and packaging configuration. Ensure the selected variant matches the required tape and reel specifications for automated assembly processes. Cross-reference the active production status with the latest datasheet revision to guarantee compliance with current manufacturing standards.

Selection Notes

Select this component when designing systems requiring multiple differential receivers within a single integrated circuit. Verify that the application environment remains within the specified 0°C to 70°C temperature range. Confirm that the power supply voltage stays strictly between 4.75V and 5.25V to maintain electrical characteristics. Ensure the PCB layout accommodates the 16-pin SOIC package dimensions and thermal requirements.

Part Context

This device belongs to the DS3486 family of quad line receivers produced by Texas Instruments. It serves as a direct replacement for older National Semiconductor equivalents, maintaining pin compatibility with the MC3486 series. The product line focuses on providing robust differential reception for standard industrial communication interfaces while offering TRI-STATE functionality for bus sharing applications.

Replacement Considerations

The DS3486M/NOPB is a pin-compatible alternative to the discontinued DS3486M. Designers should verify that the active status of the NOPB variant aligns with long-term supply requirements before finalizing the schematic.
