SN74HC688DWR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC688DWR is 25 MHz.
  • The SN74HC688DWR requires a single 2-V to 6-V power supply, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper power supply decoupling.
  • The maximum input voltage that the SN74HC688DWR can tolerate is 7 V, but it's recommended to keep the input voltage within the recommended operating range of 2 V to 6 V to ensure reliable operation.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low and disabled when OE is high. It's recommended to tie OE to GND or VCC depending on the desired output state.
  • The propagation delay of the SN74HC688DWR is typically around 10 ns to 15 ns, depending on the operating frequency and voltage.
