74HCT86D,653 datasheet by NXP Semiconductors

74HCT86D,653 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74HCT86D,653?
  The maximum operating frequency of the 74HCT86D,653 is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the 74HCT86D,653 is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 5V power supply, and decouple the power supply lines with 100nF capacitors as close to the device as possible. Additionally, use a 10uF capacitor to decouple the power supply lines at the power entry point.
• What is the maximum input voltage that can be applied to the 74HCT86D,653?
  The maximum input voltage that can be applied to the 74HCT86D,653 is 5.5V, which is the absolute maximum rating. However, it is recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V to ensure proper operation.
• Can I use the 74HCT86D,653 in a 3.3V system?
  No, the 74HCT86D,653 is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
• How do I handle unused inputs on the 74HCT86D,653?
  Unused inputs on the 74HCT86D,653 should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
