Functional Features

• Synchronous operation with a common clock pulse
• Up or down counting mode selectable using the UD input
• Parallel load capability for presetting the counter value
• Terminal count output (TC) indicates when the counter reaches its maximum value
• Master reset (MR) input for resetting the counter to zero

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient counting/dividing tasks - Versatile functionality with selectable up/down counting modes - Parallel load capability enables easy presetting of counter values - Compact SOIC package offers space-saving integration

Disadvantages: - Limited number of counting stages (4 bits) - Requires an external clock source for operation

Working Principles

The SN74F169DRE4 is a synchronous counter that operates based on the clock pulses received at the CP input. The counter can count up or down depending on the state of the UD input. When the counter reaches its maximum value, the terminal count output (TC) is activated. The counter can be preset to a specific value using the parallel load (P) input. The master reset (MR) input resets the counter to zero.

Detailed Application Field Plans

The SN74F169DRE4 is commonly used in various applications such as:

1. Digital frequency division circuits
2. Event counting systems
3. Timekeeping and clock generation circuits
4. Industrial automation and control systems
5. Communication equipment
6. Automotive electronics
