CD74HCT564E datasheet by Texas Instruments

CD74HCT564E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT564E can handle?
  The CD74HCT564E can handle clock frequencies up to 100 MHz.
• How do I ensure that the CD74HCT564E is properly powered?
  The CD74HCT564E requires a power supply voltage (VCC) of 4.5V to 5.5V, and it is 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 CD74HCT564E?
  The propagation delay of the CD74HCT564E is typically around 10ns to 15ns, depending on the operating conditions and load capacitance.
• Can I use the CD74HCT564E in a 3.3V system?
  No, the CD74HCT564E is not recommended for use in 3.3V systems, as it is designed to operate at 5V. Using it in a 3.3V system may result in reduced performance, increased power consumption, or even damage to the device.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin should be connected to a logic low (GND) to enable the outputs, and to a logic high (VCC) to disable the outputs. It is recommended to use a pull-down resistor to ensure that the OE pin is properly biased.
