Functional Features

• CD74HC93M is a 4-bit binary ripple counter that can count up to 16 different states.
• It has two independent clock inputs (CLKA and CLKB) for counting in different modes.
• The counter can be cleared to its initial state using the clear input (CLR).
• Buffered inputs and outputs ensure signal integrity and ease of integration into digital systems.
• Schmitt trigger inputs provide hysteresis, allowing for noise immunity.

Advantages

• High-speed operation enables efficient counting in time-critical applications.
• Wide operating voltage range allows compatibility with various power supply configurations.
• Low power consumption makes it suitable for battery-powered devices.
• Schmitt trigger inputs enhance noise immunity, ensuring reliable operation.
• Symmetrical output characteristics simplify circuit design.

Disadvantages

• Limited maximum operating frequency compared to some other ICs.
• Only supports binary counting up to 16 states.

Working Principles

CD74HC93M operates based on the principle of binary counting. It counts up by one for each clock pulse received at either CLK A or CLK B input. The counter can be cleared to its initial state using the CLR input. The carry output (CO) provides a signal when the counter reaches its maximum count, allowing for cascading multiple counters if required.
