Programmable Timers And Oscillators Procurement Notes

Verify package type and suffix details when ordering. The 'TA' suffix indicates the SOT23-5 package. The 'E' suffix denotes lead-free and green material compliance. Confirm availability with the manufacturer as some variants may require direct contact. Ensure external R/C values match the desired timer duration and oscillator frequency requirements.

Programmable Timers And Oscillators Selection Notes

Select this component for applications requiring a simple, low-cost timer solution with minimal external components. Ensure the operating temperature range of 0°C to 85°C meets system requirements. Verify that the load connected to the Relay pin does not exceed the DC output current limits. Consider the external R/C tolerance for precise timing accuracy.

Programmable Timers And Oscillators Part Context

The PT8A2515 is part of the PT8A series of mixed-signal CMOS LSI chips. This specific model focuses on basic timer functionality with reset capabilities.
