Functional Features

• The CD74HC93M96G4 is a synchronous counter, meaning that the outputs change simultaneously with the clock input.
• It has a ripple carry output (RCO) which can be used to cascade multiple counters for higher bit counts.
• The counter can be reset to its initial state by applying a high-level signal to the RCO pin.

Advantages and Disadvantages

Advantages

• High-speed operation allows for efficient counting and timing applications.
• CMOS logic provides low power consumption.
• Compact SOIC package enables easy integration into circuit designs.
• Ripple carry output facilitates cascading of multiple counters.

Disadvantages

• Limited to 4-bit counting, may not be suitable for applications requiring higher bit counts.
• Requires an external clock signal for proper operation.

Working Principles

The CD74HC93M96G4 operates based on the principle of binary counting. Each time a clock pulse is received at the CLK input, the counter increments its internal value by one. The outputs (Q0-Q3) represent the binary representation of the current count value. When the maximum count value (15 in this case) is reached, the counter resets to zero.

Application Field Plans

The CD74HC93M96G4 can be used in various digital applications, including:

1. Frequency Dividers: The counter can be used to divide the frequency of an input signal by powers of two.
2. Timers: It can be utilized as a basic timer in circuits that require precise timing intervals.
3. Sequential Logic Circuits: The counter can serve as a building block for more complex sequential logic circuits, such as shift registers or state machines.

Alternative Models

• SN74HC93N
• CD4017BE
