ICM7555ESA

Programmable Timers And Oscillators Overview

The ICM7555ESA is a single-channel CMOS general-purpose timer in an 8-SOIC package. It operates within a supply voltage range of 2V to 16.5V and supports frequencies up to 500kHz. The device draws a typical supply current of 30µA at 5V, enabling extended battery life. It features TTL-compatible inputs, adjustable duty cycles, and low input currents for the TRIGGER, THRESHOLD, and RESET pins. The unit functions reliably across an industrial temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Feature Summary

• Wide operating voltage range from 2V to 16.5V
• TTL compatible with high-impedance inputs
• No crowbarring of supply during output transitions

Programmable Timers And Oscillators Applications

• Pulse-width modulation (PWM) generation
• Precision timing and time delay circuits
• Sequential timing control
• Missing pulse detection systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'ESA' corresponds to the -40°C to +85°C temperature grade and SOIC-8 package. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the ordering code matches the exact pinout and electrical specifications required for the target application.

Programmable Timers And Oscillators Selection Notes

Select this component when low quiescent current is critical compared to bipolar 555 timers. The ICM7555 eliminates the need for power-supply decoupling capacitors due to negligible current spikes during switching. Use external resistors and capacitors to set precise timing intervals or oscillation frequencies based on the provided formulas.

Programmable Timers And Oscillators Part Context

This part belongs to the ICM7555/ICM7556 family of general-purpose timers manufactured by Analog Devices Inc./Maxim Integrated. The ICM7555 provides a single timer channel, whereas the ICM7556 offers dual channels. Both utilize CMOS technology to achieve superior power efficiency over traditional bipolar counterparts.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other ICM7555 variants such as ICM7555IPA or ICM7555ISA, noting differences in temperature ranges and packaging. Bipolar equivalents like the NE555 require additional decoupling components due to higher supply current spikes.
