ICM7555ISA+

Programmable Timers And Oscillators Overview

The ICM7555ISA+ is a single general-purpose CMOS timer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2V to 18V and supports an operating temperature range of -20°C to +85°C. The device features extremely low supply current, typically 30µA at 5V, making it suitable for battery-powered systems. It provides TTL-compatible outputs with a maximum oscillation frequency of 500kHz and includes adjustable duty cycle capabilities in astable mode.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix ISA+ against the manufacturer's ordering information to confirm package type and RoHS compliance status. Ensure the required operating temperature range aligns with the -20°C to +85°C specification provided for this variant. Cross-reference the datasheet revision history for any updates to electrical characteristics or absolute maximum ratings before finalizing procurement specifications.

Programmable Timers And Oscillators Selection Notes

Select the ICM7555ISA+ when low power consumption is critical compared to standard bipolar 555 timers. The SOIC-8 surface mount package is appropriate for space-constrained designs. Verify that the external timing components can support the high input impedance requirements to maintain accuracy. Consider the 500kHz maximum frequency limit for high-speed oscillator applications.

Programmable Timers And Oscillators Part Context

This component belongs to the ICM7555/ICM7556 family of general-purpose RC timers. The ICM7555 variant contains a single timer circuit, whereas the ICM7556 contains dual timers. Both share similar CMOS architecture designed to replace older bipolar timer technologies with improved power efficiency and performance characteristics.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include the ICM7555ESA+, which offers an extended industrial temperature range of -40°C to +85°C in the same SOIC-8 package. Other variants such as ICM7555IPA provide PDIP packaging options if through-hole mounting is required.
