CD74HCT393E datasheet by Texas Instruments

CD74HCT393E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT393E can handle?
  The CD74HCT393E can handle clock frequencies up to 30 MHz.
• How do I ensure that the CD74HCT393E is properly powered?
  The CD74HCT393E requires a power supply voltage (VCC) of 4.5V to 5.5V, 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 maximum input voltage that the CD74HCT393E can tolerate?
  The CD74HCT393E can tolerate input voltages up to 7V, but it's recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V to ensure proper operation.
• How do I reset the CD74HCT393E counter?
  The CD74HCT393E has a asynchronous reset input (MR) that can be used to reset the counter. When the MR input is low, the counter is reset to zero.
• Can I use the CD74HCT393E as a frequency divider?
  Yes, the CD74HCT393E can be used as a frequency divider. By connecting the Q output to the CLK input, the CD74HCT393E can be used to divide the input clock frequency by 2, 4, 8, or 16.
