SN74HC688DW datasheet by Texas Instruments

SN74HC688DW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC688DW can handle?
  The SN74HC688DW can handle clock frequencies up to 30 MHz.
• How do I ensure that the SN74HC688DW is properly powered?
  The SN74HC688DW requires a single 2V to 6V 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.
• What is the propagation delay of the SN74HC688DW?
  The propagation delay of the SN74HC688DW is typically around 10ns to 15ns, depending on the operating conditions and load capacitance.
• Can I use the SN74HC688DW in a 3.3V system?
  Yes, the SN74HC688DW is compatible with 3.3V systems, but ensure that the input signals are within the recommended input voltage range of 0.8V to VCC + 0.5V.
• How do I handle the output enable (OE) pin?
  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).
