SP485EN-EV

Drivers, Receivers, Transceivers Overview

The SP485EN-EV is a half-duplex transceiver manufactured by EVVO, designed for RS-422 and RS-485 communication protocols. It features one driver and one receiver within an 8-SOP surface-mount package. The device operates on a supply voltage range of 4.75V to 5.25V and supports data rates up to 2.5Mbps. It functions reliably across a temperature range of -40°C to 85°C (TA). Key electrical specifications include a receiver hysteresis of 70mV. The component is RoHS3 compliant and classified under ECCN EAR99.

• Suitable for industrial environments with extended temperature ratings

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and security networks
• Multi-drop communication bus architectures

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as EVVO against official datasheets, as this part number may represent a specific vendor's variant or rebranding of a standard RS-485 transceiver. Confirm the 8-SOP package dimensions match your PCB footprint requirements. Ensure the 2.5Mbps speed rating meets your system's bandwidth needs, as higher-speed alternatives exist in the broader market.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a cost-effective, low-speed RS-485 solution is required for robust noise immunity in industrial settings. The 70mV hysteresis provides improved noise rejection on noisy lines compared to non-hysteretic receivers. Verify that the 8-SOP package is compatible with your assembly process, as through-hole options like SOP-8 equivalents might be needed for different manufacturing constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the family of low-power BiCMOS RS-485 transceivers. Similar parts from other manufacturers often share pinouts and functional descriptions but may differ in ESD protection levels or maximum data rates. The SP485EN-EV specifically targets applications where moderate speed and wide operating temperature are prioritized over ultra-high throughput.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the Exar SP485EN-L or generic SP485EN clones, provided the 2.5Mbps rate and 8-SOP package are acceptable. Verify that replacement parts maintain the same 70mV receiver hysteresis and 4.75V-5.25V supply range to ensure circuit compatibility without redesign.
