ICM7224IPL,LCD Display Controller IC- 4½ Digit Counter/Decoder/Driver, 40-Pin DIP

The ICM7224IPL is a 4½ digit LCD Display Controller IC designed for precise digital counting, decoding, and driving applications. It directly interfaces with non-multiplexed liquid crystal displays (LCDs), featuring integrated segment decoders, leading zero blanking, store and reset inputs, and a carry output for cascading multiple ICs to handle more than 4½ digit displays.

. This IC operates with a low power supply current, making it ideal for battery-operated devices and other low-power applications. It supports a wide operating voltage range from 3V to 5V and is capable of counting frequencies up to 25 MHz, making it suitable for use in frequency counters, tachometers, hour meters, and totalizers.

• LCD Display Driver: Directly drives a 4½ digit non-multiplexed liquid crystal display (LCD) for easy display interfacing.
• High-Speed Counting: Handles input counting frequencies up to 25 MHz, ideal for applications needing rapid data processing.
• Low Power Consumption: Consumes minimal power, with a typical operating current of 10 µA, making it suitable for low-power devices.
• Integrated Decoders and Control: Includes segment decoders, leading zero blanking, and store/reset inputs for flexible control options.
• Cascading Capability: Can be cascaded to manage counting for 8 or more digits, suitable for advanced counting tasks.
• Wide Temperature Range: Supports operation from -20°C to +85°C, ensuring reliable performance in various environments.
