Oscillators Procurement Notes

Verify the specific manufacturer designation, as some sources list ABRACON while others specify ILSI America LLC for the ISM95 series. Confirm that the AH suffix corresponds to the correct voltage and pinout specifications required by your circuit design. Ensure the datasheet matches the exact part number to avoid discrepancies in electrical characteristics or package dimensions during integration.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator with enable/disable capability is required. The 2.5V to 3.3V supply range suits modern low-voltage digital designs. Consider the 4MHz frequency and CMOS output compatibility with standard logic families. Verify thermal requirements against the -40°C to +85°C operating range for environmental suitability.
