Disadvantages: - Limited counting range: Being a 4-bit counter, it can only count up to 15 before resetting to zero. - Limited package options: The CD74HCT161MT is only available in the TSSOP-16 package.
Working Principles
The CD74HCT161MT is a synchronous binary counter that counts up or down based on the clock signal. When the clock input receives a rising edge, the counter increments its value by one. The parallel load input allows loading of initial values into the counter, and the clear input resets the counter to zero. The carry output indicates when the counter reaches its maximum value.
Detailed Application Field Plans
The CD74HCT161MT is commonly used in various applications, including:
- Digital frequency counters
- Industrial automation systems
- Communication equipment
- Automotive electronics
- Test and measurement instruments
