Functional Features
- The SN7497NG4 is a 6-bit sequential counter with an asynchronous clear function.
- It can be used as a frequency divider or a binary counter.
- The counter advances on the rising edge of the clock signal.
- The asynchronous clear input allows for immediate resetting of the counter to zero.
Advantages and Disadvantages
Advantages: - High-speed operation - Low-power consumption - TTL-compatible inputs and outputs - Wide operating temperature range
Disadvantages: - Limited maximum clock and counting frequencies - Limited number of data inputs
Working Principles
The SN7497NG4 operates based on the principle of sequential counting. It counts from 0 to 63 (in binary) and then wraps around back to 0. The counter advances by one on each rising edge of the clock signal, unless the asynchronous clear input is activated, which resets the counter to zero.
Detailed Application Field Plans
The SN7497NG4 can be used in various applications, including: 1. Frequency division in digital communication systems 2. Clock generation in microcontrollers and microprocessors 3. Pulse generation in timing circuits 4. Event counting in industrial automation systems
