SP489CS-L

Drivers, Receivers, Transceivers Overview

The SP489CS-L is a low-power quad differential line receiver manufactured by Sipex, designed to meet RS-485 and RS-482 standards. It operates from a single +5V supply and features independent receiver enable controls for each pair of receivers. The device utilizes BICMOS technology and provides tri-state outputs with a wide common-mode input range of -7V to +12V. Packaged in an 8-pin SOIC (SOP) format, it includes fail-safe circuitry that forces a logic high output when inputs are floating. The component supports industrial temperature ranges and ensures reliable data transmission in multi-point communication networks.

Drivers, Receivers, Transceivers Feature Summary

• Independent receiver enable controls allow selective activation of individual receiver pairs
• Fail-safe design forces a logic high state when differential inputs remain unconnected
• Wide common-mode input range accommodates significant signal voltage variations

Drivers, Receivers, Transceivers Applications

• RS-485 multi-drop communication bus systems
• Industrial process control network interfaces
• Building automation and security system data links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix designation against official Sipex documentation to confirm package type and environmental compliance status. Ensure the source document explicitly identifies the manufacturer as Sipex or its successor entity rather than a distributor. Cross-reference the RoHS compliance marking with current regulatory requirements before integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when independent control of multiple receiver channels is required within a single package. Compare propagation delay specifications against system timing constraints to ensure signal integrity. Verify that the operating temperature range aligns with the intended deployment environment and that the supply voltage matches the target power rail.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Sipex family of RS-485/RS-422 interface devices, which also includes models like the SP488. While the SP488 shares similar electrical characteristics, it utilizes a common enable pin for all receivers. The SP489 variant offers greater flexibility in managing half-duplex traffic by allowing granular control over individual receiver pairs.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the SN75176 and LTC489. These alternatives offer pin-compatible upgrades with comparable electrical performance. Verify that the replacement device maintains the same independent enable functionality and voltage levels before implementation.
