SN74LS02D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74LS02D?
  The maximum frequency of operation for the SN74LS02D is typically around 35 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74LS02D is properly powered?
  To ensure proper operation, the SN74LS02D should be powered with a stable 5V supply, and decoupling capacitors should be used to filter out noise and voltage spikes.
• What is the maximum current that the SN74LS02D can sink or source?
  The SN74LS02D can sink or source up to 16 mA of current per output, but this should be limited to 8 mA per output to ensure reliable operation.
• How do I handle unused inputs on the SN74LS02D?
  Unused inputs on the SN74LS02D should be tied to a logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
• Is the SN74LS02D compatible with 3.3V logic?
  The SN74LS02D is a 5V device, but it can be used with 3.3V logic with proper level shifting or voltage translation. However, this may require additional circuitry and careful design consideration.
