ICM7555ID/01,112

Programmable Timers And Oscillators Overview

The ICM7555ID/01,112 is a general-purpose CMOS timer manufactured by NXP Semiconductors. It serves as a direct replacement for standard NE/SE555 timers with improved performance characteristics. The device operates within a supply voltage range of 3 V to 16 V and supports an ambient temperature range of -40 °C to +85 °C. Key electrical parameters include a typical supply current of 80 μA, extremely low trigger, threshold, and reset currents of 20 pA, and a guaranteed high-speed operation up to 500 kHz. The output driver provides rail-to-rail swing capable of driving TTL or CMOS loads.

Programmable Timers And Oscillators Feature Summary

• Low supply current: 80 μA (typical)
• Extremely low input currents: 20 pA (typical) for TRIGGER, THRESHOLD, and RESET
• High-speed operation: 500 kHz guaranteed frequency
• Wide operating supply voltage range: 3 V to 16 V over full automotive temperatures

Programmable Timers And Oscillators Applications

• Time delay generation
• Pulse width modulation

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix /01,112 against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure compatibility with the required industrial temperature range (-40 °C to +85 °C) defined for the ID variant. Cross-reference the datasheet revision history for any updates to limiting values or application notes before finalizing procurement specifications.

Programmable Timers And Oscillators Selection Notes

Select this component when replacing bipolar 555 timers in applications requiring significantly lower power consumption and higher input impedance. The ICM7555 allows the use of higher-impedance timing elements for longer time constants without decoupling capacitors on the CONTROL_VOLTAGE pin. Verify that the load requirements do not exceed the output source/sink capabilities specified in the characteristics table.

Programmable Timers And Oscillators Part Context

The ICM7555 series includes variants such as ICM7555CD (commercial, 0 °C to +70 °C) and ICM7555CN (commercial DIP). The ID variant specifically denotes the industrial temperature grade (-40 °C to +85 °C). The /01,112 suffix indicates the specific tape-and-reel packaging configuration provided by NXP Semiconductors.

Programmable Timers And Oscillators Replacement Considerations

The ICM7555 is designed as an exact equivalent for most NE/SE555 applications. Direct substitutes from other manufacturers may vary in input bias currents or output drive strength. Verify that alternative components support the same 3 V to 16 V operating range and 500 kHz frequency guarantee.
