EL1517BILZ-T7

Overview

The EL1517BILZ-T7 is a high-speed, low-power differential line driver manufactured by Elantec. It features a wide supply voltage range from 4.75 V to 11 V and supports data rates up to 200 Mbps. The device integrates a 1.2 kV ESD protection structure on its inputs and outputs, ensuring robustness in harsh environments. Key electrical parameters include a typical propagation delay of 3 ns and a skew of 1 ns. It operates within a temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package.

Feature Summary

• Integrated 1.2 kV electrostatic discharge (ESD) protection on input and output pins for enhanced reliability
• Low power consumption suitable for battery-operated or energy-efficient systems
• High-speed differential signaling capability supporting data rates up to 200 Mbps
• Wide single-supply voltage operation ranging from 4.75 V to 11 V

Applications

• RS-422 and RS-485 communication interfaces
• Industrial process control networks
• Data acquisition systems requiring long-distance signal transmission
• Building automation and security systems

Procurement Notes

Verify the specific suffix 'T7' indicates tape and reel packaging when ordering. Confirm the 'BI' designation corresponds to the industrial temperature grade (-40°C to +85°C). Check current availability as this component may be subject to end-of-life status or limited production runs depending on the manufacturer's portfolio updates. Ensure compatibility with existing PCB footprints for the 8-lead SOIC package.

Selection Notes

Select this component when differential signaling with integrated ESD protection is required for RS-422/485 applications. Compare propagation delay and skew specifications against system timing requirements. Consider the operating temperature range if the application involves extreme environmental conditions. Verify that the supply voltage range aligns with the system's power rails. Evaluate pinout compatibility if replacing legacy drivers.

Part Context

The EL1517 series represents Elantec's family of high-speed differential line drivers designed for robust communication links. The EL1517BILZ-T7 specifically targets industrial and commercial applications needing reliable data transmission over twisted-pair cables. It complements other Elantec interface products by offering integrated protection features that reduce the need for external components, simplifying board design and improving overall system resilience against electrical transients.

Replacement Considerations

Direct replacements may include the EL1517BLZ or EL1517IZ variants, differing primarily in temperature rating or packaging. Cross-reference pinouts and electrical characteristics carefully. Some generic RS-422/485 transceivers may serve as functional substitutes but might lack the integrated ESD protection or specific speed capabilities.
