Programmable Timers And Oscillators Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated for the ICM7556ISD+. Confirm the 14-SOIC package type and -20°C to +85°C operating temperature range match project requirements. Ensure compliance with RoHS3 specifications if environmental standards are mandatory for the assembly process.

Programmable Timers And Oscillators Selection Notes

Select this component when dual independent timers are required in a compact surface-mount form factor. The CMOS architecture allows for high-impedance timing components, reducing system power consumption compared to bipolar alternatives. Verify that the 500kHz frequency limit meets the application's speed requirements.

Programmable Timers And Oscillators Part Context

This part belongs to the ICM7555/ICM7556 family of CMOS timers. The ICM7556 provides two independent timer channels, whereas the ICM7555 offers a single channel. Both share similar electrical characteristics but differ in pin count and internal configuration.
