SN74ALS688N Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74ALS688N is 100 MHz.
  • The SN74ALS688N requires a single 5V 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 propagation delay of the SN74ALS688N is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
  • No, the SN74ALS688N is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in reduced performance or even damage to 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).
