SN74AHC273DBR datasheet by Texas Instruments

SN74AHC273DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHC273DBR?
  The maximum operating frequency of the SN74AHC273DBR is 100 MHz, but it can vary depending on the output load and the system's noise margin.
• How do I ensure that the SN74AHC273DBR is properly powered?
  To ensure proper power supply, connect VCC to a 2.0-V to 5.5-V power supply, and GND to the system's ground. Also, decouple the power supply with a 0.1-μF capacitor to reduce noise and ensure stable operation.
• What is the maximum input voltage that the SN74AHC273DBR can tolerate?
  The maximum input voltage that the SN74AHC273DBR can tolerate is 5.5 V, which is the absolute maximum rating. However, it's recommended to keep the input voltage within the recommended operating range of 2.0 V to 5.5 V to ensure reliable operation.
• Can I use the SN74AHC273DBR in a 3.3-V system?
  Yes, the SN74AHC273DBR can be used in a 3.3-V system. In fact, it's a popular choice for 3.3-V systems due to its wide operating voltage range of 2.0 V to 5.5 V.
• How do I handle the unused inputs of the SN74AHC273DBR?
  Unused inputs should be tied to a logic level (either VCC or GND) to prevent them from floating, which can cause unpredictable behavior. It's recommended to tie them to GND to minimize power consumption.
