CD74HC32EE4 datasheet by Texas Instruments

CD74HC32EE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HC32EE4?
  The maximum operating frequency of the CD74HC32EE4 is 25 MHz, but it can vary depending on the supply voltage and load capacitance.
• How do I ensure that the CD74HC32EE4 is properly powered?
  To ensure proper power supply, connect VCC to a 2.0-V to 6.0-V power source, and GND to the system ground. Also, decouple the power supply with a 0.1-μF capacitor to reduce noise and ensure stable operation.
• What is the input voltage threshold for the CD74HC32EE4?
  The input voltage threshold for the CD74HC32EE4 is typically around 1.3V to 1.7V for a logic high and 0.5V to 0.7V for a logic low, but it can vary depending on the supply voltage and temperature.
• Can I use the CD74HC32EE4 in a 3.3V system?
  Yes, the CD74HC32EE4 can operate in a 3.3V system, but the input voltage threshold may be affected. It's recommended to check the datasheet for specific voltage and current requirements.
• How do I handle unused inputs on the CD74HC32EE4?
  Unused inputs on the CD74HC32EE4 should be tied to a logic high or low level to prevent floating inputs, which can cause unpredictable behavior. It's recommended to tie them to VCC or GND through a 1-kΩ resistor.
