IL 711-2E

Overview

The IL711-2E is a two-channel digital isolator from NVE’s IsoLoop family, utilizing Giant Magnetoresistance (GMR) technology for galvanic isolation. It supports data rates up to 110 Mbps with a typical propagation delay of 15 ns and rise/fall times of 1 ns. The device operates on a single supply voltage between 3 V and 5.5 V, drawing a maximum input current of 15 μA. It provides 2500 Vrms isolation voltage and withstands common-mode transients of 100 kV/μs. Available in an 8-pin PDIP package, it functions within a temperature range of -40°C to 125°C.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission without optical components
• Provides robust galvanic isolation with high common-mode transient immunity
• Features ultra-low power consumption suitable for battery-operated systems
• Offers CMOS compatibility for direct interface with logic circuits

Applications

• Isolated data transmission in industrial communication networks
• Signal isolation for ADC and DAC interfaces
• Fieldbus isolation in automation systems
• Logic level shifting between different voltage domains

Procurement Notes

Verify the specific suffix '2E' confirms the 8-pin PDIP package and unidirectional channel configuration. Confirm the operating temperature grade matches the application requirements, as variants may differ. Ensure compliance with UL and IEC standards if required by the target system design. Cross-reference the manufacturer part number directly with official NVE documentation to avoid substitution errors.

Selection Notes

Select this component when low power consumption and high speed are critical constraints. The GMR technology offers superior reliability compared to optical isolators in harsh environments. Consider the 8-pin PDIP form factor for through-hole assembly needs. Evaluate the 2500 Vrms isolation rating against the system's safety requirements. Compare input current specifications against other isolators to ensure power budget compliance.

Part Context

The IL711-2E belongs to NVE’s IsoLoop series, which distinguishes itself by using magnetic sensing rather than light or capacitance for isolation. This family includes various channel counts and package options. The IL711 base model typically denotes dual-channel functionality. The '-2E' suffix specifies the physical package and pinout configuration for this particular variant.

Replacement Considerations

Direct replacements include other IL711 variants with identical electrical characteristics but different packages, such as IL711-3E for SOIC. Verify that any substitute maintains the 110 Mbps data rate and 15 μA input current limits. Check for package compatibility if board space is constrained.
