ICM7555IPA

Programmable Timers And Oscillators Overview

The Intersil ICM7555IPA is a general-purpose CMOS timer IC housed in an 8-pin PDIP package. It operates on a supply voltage range of 2 V to 18 V and supports output compatibility with both CMOS and TTL logic families. The device features a low quiescent current of 60 µA, enabling efficient power consumption. It functions as a single internal timer capable of generating precise time delays, pulse widths, and oscillation frequencies up to 1 MHz. The component is designed for surface mount or through-hole applications within commercial temperature ranges.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'IPA' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like ICM7555IBAZ or ICM7555IPAZ. Cross-reference the RoHS compliance status directly with the provided specification sheet.

Programmable Timers And Oscillators Selection Notes

Select the ICM7555IPA when a low-power, general-purpose timer is required for battery-operated or precision timing applications. Compare the PDIP-8 package constraints against available PCB space. Verify that the 2 V minimum supply voltage meets the system requirements, as some standard 555 timers require higher voltages. Confirm the 1 MHz maximum frequency is sufficient for the intended clock or oscillator application.

Programmable Timers And Oscillators Part Context

The ICM7555 series represents a CMOS version of the classic 555 timer, offering significantly lower power consumption compared to bipolar counterparts. Intersil, now part of Renesas Electronics, manufactures this component as part of their broader portfolio of analog and mixed-signal integrated circuits. The ICM7555IPA specifically denotes the plastic dual in-line package variant within this family.
