74HCT4094D,112 datasheet by NXP Semiconductors

74HCT4094D,112 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HCT4094D,112?
  The maximum clock frequency for the 74HCT4094D,112 is 25 MHz, but it's recommended to check the timing diagrams and clock frequency limitations in the datasheet for specific applications.
• How do I ensure that the 74HCT4094D,112 is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF decoupling capacitor between VCC and GND, and consider adding a 10uF bulk capacitor for larger circuits. Also, ensure that the power supply can handle the maximum current required by the device.
• Can I use the 74HCT4094D,112 in a 3.3V system?
  No, the 74HCT4094D,112 is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in incorrect operation or damage to the device.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (GND) and disabled when OE is high (VCC). Ensure that the OE pin is properly connected and controlled in your design to avoid output contention or incorrect operation.
• What is the maximum output current that the 74HCT4094D,112 can sink or source?
  The 74HCT4094D,112 can sink or source up to 6mA per output pin, but it's recommended to check the output current limitations in the datasheet for specific applications and to ensure that the device is not overloaded.
