SN74LS02N datasheet by Texas Instruments

SN74LS02N Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74LS02N?
  The maximum frequency of operation for the SN74LS02N is typically around 35 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74LS02N is properly powered?
  To ensure proper operation, the SN74LS02N 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 SN74LS02N can sink or source?
  The SN74LS02N 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.
• Can the SN74LS02N be used in a 3.3V system?
  While the SN74LS02N is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the noise margin may be reduced.
• How do I handle unused inputs on the SN74LS02N?
  Unused inputs on the SN74LS02N should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
