Description and Introduction

Synchronous Binary Counter with Synchronous Clear # **MM74HC163MX: A High-Performance Synchronous Binary Counter**  

The MM74HC163MX is a high-speed synchronous 4-bit binary counter designed for precision timing and counting applications. Built with advanced CMOS technology, this component offers reliable performance, low power consumption, and compatibility with TTL inputs, making it a versatile choice for digital circuit design.  

## **Key Features**  

- **Synchronous Operation**: All flip-flops are clocked simultaneously, ensuring accurate counting without ripple delays.  
- **4-Bit Binary Counting**: Supports counting from 0 to 15 (binary), with synchronous reset functionality for precise control.  
- **Parallel Load Capability**: Allows preset values to be loaded via parallel inputs, enhancing flexibility in circuit design.  
- **High-Speed Performance**: With propagation delays as low as 13 ns, the MM74HC163MX is ideal for high-frequency applications.  
- **Low Power Consumption**: CMOS technology ensures minimal power dissipation, making it suitable for battery-operated devices.  
- **Wide Operating Voltage**: Functions reliably between 2V and 6V, accommodating various logic level requirements.  

## **Applications**  

The MM74HC163MX is widely used in digital systems where precise counting and timing are critical. Common applications include:  
- Frequency dividers and clock generators  
- Digital timers and event counters  
- Microcontroller-based systems  
- Industrial automation and control circuits  

## **Reliability and Compatibility**  

Engineers and designers favor the MM74HC163MX for its robust performance and ease of integration. Its TTL-compatible inputs ensure seamless interfacing with existing logic families, while its synchronous design minimizes timing errors.  

For projects requiring a dependable, high-speed binary counter, the MM74HC163MX delivers efficiency, accuracy, and durability—making it an essential component in modern digital electronics.

Application Scenarios & Design Considerations

Synchronous Binary Counter with Synchronous Clear

Alternative Part Number

  • SN74HC163DR --: Same 4-bit synchronous binary counter function in the 74HC logic family, widely available and pin-compatible in SOIC-16 package.
  • CD74HC163E --: Harris/Intersil 74HC163 equivalent with identical counter functionality and logic levels, suitable direct functional replacement.
  • MC74HC163ADG --: Motorola/ON 74HC163 synchronous counter with matching pinout and electrical characteristics, good second-source option.
