ICM7217AIPI

Programmable Timers And Oscillators Overview

The ICM7217AIPI is a monolithic CMOS device integrating a 4-digit, 7-segment LED display driver with a presettable up/down counter and comparison register. It operates on a single 5V supply and features multiplexed BCD input/output for interfacing with thumbwheel switches or digital logic. The component includes dedicated inputs for up/down control, store, and reset functions. Designed for low power consumption, it directly drives LED displays without external transistors, supporting cascading for expanded digit counts.

Programmable Timers And Oscillators Feature Summary

• Integrated 4-digit, 7-segment LED display driver with direct drive capability
• Presettable up/down counter and comparison (predetermining) register
• Interfaces directly with thumbwheel switches or external digital logic
• Supports cascading for multi-digit expansion

Programmable Timers And Oscillators Applications

• Digital counters requiring preset values
• Systems utilizing thumbwheel switch inputs
• LED display instrumentation panels

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-20°C to +85°C) and 'PI' denotes the 28-pin PDIP package. Confirm RoHS compliance status as '+'. Check current availability through authorized distributors, as lead times may vary based on manufacturing schedules.

Programmable Timers And Oscillators Selection Notes

Select this component when a combined counting and display driving function is required in a single IC. Ensure the application utilizes 7-segment LEDs and requires a 4-digit capacity. Verify that the interface logic matches the multiplexed BCD input requirements and that the operating voltage aligns with the specified 5V nominal supply.

Programmable Timers And Oscillators Part Context

This part belongs to the ICM7217 family of presettable up/down counters. It is functionally compatible with other manufacturers' second-source equivalents. The AIPI variant specifies the industrial temperature grade and plastic DIP packaging, distinguishing it from ceramic or commercial grade variants within the same functional family.

Programmable Timers And Oscillators Replacement Considerations

Pin-for-pin second sources exist from Intersil, Renesas, and others under the same ICM7217 designation. Verify electrical characteristics and temperature ranges match before substitution.
