ICM7217IPI+

Programmable Timers And Oscillators Overview

The ICM7217IPI+ is a four-digit, presettable LED up/down counter and decoder driver manufactured by Analog Devices Inc./Maxim Integrated. Designed for driving seven-segment displays, it features a 28-pin PDIP package with through-hole mounting. The device operates on a single 4.5 V to 5.5 V power supply and supports a maximum power dissipation of 1 W. It functions within an industrial temperature range of -20°C to +85°C, providing direct drive capabilities for LED segments while managing digit multiplexing internally.

Programmable Timers And Oscillators Feature Summary

• Four-digit presettable up/down counter with BCD output
• Integrated segment and digit drivers for direct LED display control
• Operates on a standard 5V logic supply (4.5V to 5.5V)
• Industrial temperature rating from -20°C to +85°C

Programmable Timers And Oscillators Applications

• Digital panel meters requiring up/down counting
• Presettable timer circuits
• Frequency counters with digital readout
• Industrial process control displays

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-20°C to +85°C) compared to commercial variants. Confirm the 'P' suffix corresponds to the 28-pin plastic DIP package. Ensure compatibility with existing PCB footprints for through-hole assembly before procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when a dedicated up/down counter with integrated display driving is required. The ICM7217IPI+ is suitable for applications needing presettable values and direct LED interface without external decoding logic. Consider the 200 mA maximum supply current and 1 W power dissipation limits for thermal management in enclosed designs.

Programmable Timers And Oscillators Part Context

This part belongs to the ICM7217B/I/C family of LED display drivers. The 'I' designation specifies the industrial temperature grade, distinguishing it from the 'B' (commercial) and 'C' variants. It serves as a complete solution for simple numeric display applications, replacing discrete counter and decoder chips.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include other members of the ICM7217 family such as the ICM7217BIPI+ or ICM7217CIPI+, differing primarily in operating temperature ranges. Verify pinout compatibility if substituting with generic 7-segment decoder ICs.
