SN74LS688N Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS688N is 25 MHz.
  • The SN74LS688N requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to reduce noise and ensure stable operation.
  • The typical propagation delay of the SN74LS688N is 10ns, but it can vary depending on the operating conditions and load capacitance.
  • No, the SN74LS688N is designed to operate at 5V, and using it in a 3.3V system may not guarantee proper operation or may even damage the device.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (GND) and disabled when OE is high (VCC).
