NE555DR-EV

Overview

The NE555DR-EV is a single programmable timer and oscillator integrated circuit manufactured by EVVO. It operates within an 8-SOIC surface-mount package, specifically identified as 8-SOP with a width of 3.90mm. The device supports a maximum frequency of 1 MHz and functions within a temperature range of 0°C to 70°C (TA). Electrical specifications include a supply current of 10 mA. This component is classified under programmable timers and oscillators, designed for precise timing applications in electronic circuits.

Feature Summary

• Single precision timer and oscillator functionality
• Surface-mount installation in compact 8-SOIC package
• Operates within standard industrial temperature ranges

Applications

• Timing interval generation
• Pulse width modulation
• Oscillator circuits

Procurement Notes

Verify the manufacturer part number NE555DR-EV against official EVVO documentation to ensure authenticity. Confirm that the 8-SOIC package dimensions and thermal characteristics match your design requirements. Check for specific revision codes or suffixes that may indicate minor manufacturing updates while maintaining functional equivalence. Ensure compliance with RoHS3 standards if required by your assembly process.

Selection Notes

Select this component when a single-channel timer is required in a surface-mount configuration. Consider the 1 MHz frequency limit and 10 mA supply current constraints for power management. The 0°C to 70°C operating range suits general commercial applications rather than extreme environmental conditions. Evaluate the 8-SOIC footprint compatibility with existing PCB layouts.

Part Context

This part belongs to the NE555 family of precision timers, widely used for time-delay and oscillation purposes. The EVVO variant maintains standard pinout and electrical characteristics associated with the classic 555 timer architecture. It serves as a direct replacement for similar single-timer ICs in legacy designs requiring modern surface-mount packaging solutions.

Replacement Considerations

Cross-reference with other manufacturers' NE555 variants such as Texas Instruments or STMicroelectronics equivalents. Verify pin compatibility and electrical parameter alignment before substitution. Ensure that any alternative part meets the same 8-SOIC package and temperature range specifications.
