74HC4094D,653 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC4094D?
  The maximum clock frequency for the 74HC4094D is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the 74HC4094D is properly powered and decoupled?
  To ensure proper operation, the 74HC4094D should be powered with a stable 5V supply, and decoupling capacitors (e.g., 100nF) should be placed close to the device to filter out noise and reduce electromagnetic interference (EMI).
• What is the maximum current that the 74HC4094D can sink or source?
  The 74HC4094D can sink or source up to 25mA per output pin, but it's recommended to limit the current to 10mA per pin to ensure reliable operation.
• How do I handle the asynchronous reset (RST) input on the 74HC4094D?
  The asynchronous reset (RST) input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the device is properly reset during power-up or when the reset input is asserted.
• What is the recommended layout and routing for the 74HC4094D?
  To minimize noise and signal degradation, it's recommended to keep the clock signal traces short and away from other signals, and to use a ground plane to reduce electromagnetic interference (EMI).
