CD74HC03E datasheet by Texas Instruments

CD74HC03E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC03E?
  The maximum frequency of operation for the CD74HC03E is typically around 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin is active-low, meaning that the output is enabled when OE is low and disabled when OE is high. You should connect OE to a logic low signal to enable the output, and to a logic high signal to disable the output.
• What is the recommended power-on reset (POR) circuit for the CD74HC03E?
  Texas Instruments recommends using a 0.1 μF capacitor and a 1 kΩ resistor in series to create a POR circuit for the CD74HC03E. This circuit helps to ensure that the device powers up in a known state.
• Can I use the CD74HC03E in a 5V system?
  Yes, the CD74HC03E is compatible with 5V systems, but you should ensure that the input voltage (VCC) is within the recommended operating range of 2V to 6V. Additionally, you should also consider the voltage tolerance of the device and the system's noise margin.
• How do I handle the input voltage (VIN) and output voltage (VOUT) in my design?
  The input voltage (VIN) should be within the recommended operating range of 2V to 6V, and the output voltage (VOUT) should be within the recommended operating range of 0V to VCC. You should also ensure that the input and output voltage levels are compatible with the system's logic levels.
