Description and Introduction

16-Key Encoder **Introducing the MM74C922WM: A Reliable Keypad Encoder for Modern Applications**  

The MM74C922WM is a high-performance CMOS keypad encoder designed to simplify interface design in a variety of electronic applications. This integrated circuit efficiently converts keypad inputs into corresponding digital outputs, making it an ideal choice for systems requiring user input, such as access control panels, industrial controllers, and consumer electronics.  

Engineered for precision and reliability, the MM74C922WM supports up to a 4x4 matrix keypad, providing 16 possible input combinations. Its built-in debounce circuitry ensures clean signal transitions, eliminating false triggering due to mechanical switch bounce—a common challenge in keypad-based systems. Additionally, the device features a two-key rollover function, allowing for accurate detection of simultaneous key presses.  

Operating with a wide voltage range of 3V to 15V, the MM74C922WM offers flexibility in both low-power and standard logic-level applications. Its CMOS technology ensures low power consumption, making it suitable for battery-operated devices where energy efficiency is critical. The encoder also includes an internal oscillator, reducing the need for external timing components and simplifying circuit design.  

With its compact SOIC-20 package, the MM74C922WM is well-suited for space-constrained designs while maintaining robust performance. Whether integrated into security systems, industrial automation, or consumer electronics, this keypad encoder delivers consistent, dependable operation.  

For engineers and designers seeking a proven solution for keypad interfacing, the MM74C922WM combines functionality, efficiency, and ease of integration, making it a valuable component in modern electronic systems.
