SN7404D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN7404D?
  The maximum frequency of operation for the SN7404D is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN7404D is properly powered?
  To ensure proper operation, the SN7404D should be powered with a stable voltage supply between 4.75V and 5.25V, with a maximum current draw of 20mA per inverter.
• What is the input voltage threshold for the SN7404D?
  The input voltage threshold for the SN7404D is typically around 2.0V, with a maximum input voltage of 5.5V.
• Can I use the SN7404D in a 3.3V system?
  While the SN7404D is typically used in 5V systems, it can be used in 3.3V systems with some limitations. However, the output voltage swing will be reduced, and the propagation delay may increase.
• How do I handle thermal considerations for the SN7404D?
  The SN7404D has a maximum junction temperature of 150°C. To ensure reliable operation, the device should be mounted on a suitable heat sink, and the ambient temperature should be kept below 70°C.
