Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's datasheet to confirm compliance with RoHS directives and material composition changes. Confirm that the ordering part number matches the required package style and temperature grade before procurement.

Programmable Timers And Oscillators Selection Notes

Select the SA555DRE4 when a surface-mount solution is required for standard 555 timer functionality. Ensure the design accommodates the 4.5 V minimum supply voltage and the -40°C to +85°C industrial temperature range. Verify that the 200 mA output current meets load requirements.

Programmable Timers And Oscillators Part Context

This component is part of the broader SA555 family of single precision timers. It shares functional similarities with other variants like the SA555DR but includes specific manufacturing or compliance identifiers indicated by the suffix. It serves as a surface-mount alternative to through-hole packages such as the SA555P.

Programmable Timers And Oscillators Replacement Considerations

SA555DR is a verified substitute within the same series offering identical electrical characteristics and pinout compatibility.
