Comparators Procurement Notes

Verify the specific ordering suffix 'AF' corresponds to the SOT-23-5 package configuration as documented in the official datasheet. Confirm that the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Ensure proper handling procedures are followed due to the presence of internal ESD protection mechanisms specified in the documentation.

Comparators Selection Notes

Select this component when a single-channel comparator with low power consumption is required. It is suitable for applications where the input signal can swing down to ground level while powered by a single supply rail. Consider the 1.3μs response time and 16mA output drive capability against system timing and load requirements before finalizing the design choice.

Comparators Part Context

This part belongs to the NJM390A/NJM391A series of low-power single voltage comparators. The NJM391AF variant specifically utilizes the SOT-23-5 surface-mount package. The series is designed for general-purpose use, offering high input impedance and compatibility with standard digital logic families through its versatile output stage architecture.

Comparators Replacement Considerations

The NJM390AF-TE1 is a related single-channel comparator within the same family. Verify pinout compatibility and electrical specifications such as supply current and offset voltage before substituting.
