ICM7211AIPL+

Display Drivers Overview

The ICM7211AIPL+ is a four-digit, seven-segment CMOS LCD display decoder-driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3 V to 6 V and features a maximum clock frequency of 16 kHz. The device supports 28 segment outputs and includes an onboard RC oscillator for backplane frequency generation. Designed for through-hole mounting, it utilizes a PDIP-40 package and functions reliably across an operating temperature range of -20°C to +85°C.

Display Drivers Feature Summary

• Integrates a complete onboard RC oscillator to generate the necessary backplane frequency without external components.
• Provides data input latches and digit address latches controlled by chip select inputs for direct high-speed processor interface.
• Includes backplane input/output capabilities to allow simple synchronization of slave devices to a master unit.

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Microprocessor-based digital readouts
• Direct drive LCD interfaces requiring BCD decoding

Display Drivers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead times directly with suppliers, as availability may vary. Ensure the specific suffix matches the required package and temperature grade for your design implementation.

Display Drivers Selection Notes

Select this component for applications requiring a dedicated four-digit LCD decoder with integrated timing generation. Consider the PDIP-40 through-hole package for prototyping or standard PCB layouts. Verify that the 3 V to 6 V supply range aligns with the system power architecture and that the 16 kHz clock limit meets the display refresh requirements.
