SN74LS688DW Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS688DW is 25 MHz.
  • The SN74LS688DW 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 ensure proper power supply decoupling.
  • The propagation delay of the SN74LS688DW is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
  • No, the SN74LS688DW is designed to operate at 5V, and it's not recommended to use it in a 3.3V system. Using it at a lower voltage may affect its performance and reliability.
  • 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).
