SN74AHC86DBR datasheet by Texas Instruments

SN74AHC86DBR Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74AHC86DBR?
  The maximum frequency of operation for the SN74AHC86DBR is typically around 100 MHz, but it can vary depending on the specific application, supply voltage, and output load.
• How do I ensure that the SN74AHC86DBR is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 2.0-5.5V power supply, and decouple the power supply lines with 0.1uF ceramic capacitors as close to the device as possible.
• What is the input voltage threshold for the SN74AHC86DBR?
  The input voltage threshold for the SN74AHC86DBR is typically around 0.5VCC, which means that the input signal must be above 0.5 times the supply voltage to be considered a logic high, and below 0.5 times the supply voltage to be considered a logic low.
• Can I use the SN74AHC86DBR in a 3.3V system?
  Yes, the SN74AHC86DBR is compatible with 3.3V systems, and can operate with a supply voltage as low as 2.0V. However, the output voltage levels may not be as strong as those in a 5V system.
• How do I handle unused inputs on the SN74AHC86DBR?
  Unused inputs on the SN74AHC86DBR should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
