74HC4094DB,118 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC4094DB,118?
  The maximum clock frequency is typically limited by the rise and fall times of the clock signal, but NXP recommends a maximum clock frequency of 10 MHz for this device.
• How do I ensure that the 74HC4094DB,118 is properly powered and decoupled?
  To ensure proper operation, the 74HC4094DB,118 should be powered from a stable 5V supply, and decoupling capacitors (e.g. 100nF) should be placed as close as possible to the device's power pins.
• What is the maximum current that can be sourced or sunk by the 74HC4094DB,118's outputs?
  The 74HC4094DB,118's outputs can source or sink up to 25mA, but this should be limited to 10mA or less for reliable operation.
• Can the 74HC4094DB,118 be used in a 3.3V system?
  While the 74HC4094DB,118 is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device's performance may be degraded.
• How do I handle the 74HC4094DB,118's asynchronous reset input?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g. 1kΩ) to ensure that the device is properly reset during power-up. The reset input should be driven low for at least 10ns to ensure a proper reset.
