Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix HR against official manufacturer documentation to confirm any specialized handling, environmental compliance, or packaging variations distinct from the standard ICM7556MJD variant. Ensure compatibility with existing PCB footprints for the 14-CDIP package before procurement. Cross-reference RoHS and REACH status with current regulatory requirements for the target market. Confirm that the supply voltage and temperature ranges align with the final application environment specifications.

Programmable Timers And Oscillators Selection Notes

Select this component when dual independent timing channels are required in a single package to reduce board space. Choose the CDIP package for through-hole mounting applications requiring higher mechanical stability compared to surface-mount options. Consider the 2V to 18V operating range for flexibility in various power supply architectures. Evaluate the 500kHz frequency limit to ensure it meets the timing resolution needs of the specific design without requiring external buffering or additional circuitry.

Programmable Timers And Oscillators Part Context

The ICM7556MJD/HR belongs to the ICM7555/ICM7556 family of low-power CMOS timers. While the ICM7555 provides a single timer channel, the ICM7556 offers dual channels, making it suitable for more complex timing sequences. This family serves as a CMOS-compatible alternative to traditional bipolar 555 timers, offering significantly lower power consumption and wider supply voltage operation. The MJD/HR designation indicates a specific ceramic dual in-line package variant within this product line.
