CD74HCT153E datasheet by Texas Instruments

CD74HCT153E Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HCT153E?
  The maximum operating frequency of the CD74HCT153E is 30 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the enable inputs (E1 and E2) when not in use?
  When not in use, the enable inputs (E1 and E2) should be tied to a logic high (VCC) to ensure that the device is enabled and functioning properly.
• What is the recommended power-on sequence for the CD74HCT153E?
  The recommended power-on sequence is to apply power to VCC before applying any input signals to the device. This helps to prevent any potential latch-up or damage to the device.
• Can I use the CD74HCT153E in a 5V system?
  Yes, the CD74HCT153E is compatible with 5V systems, but it's essential to ensure that the input signals do not exceed the maximum rating of 5.5V to prevent damage to the device.
• How do I determine the propagation delay of the CD74HCT153E?
  The propagation delay of the CD74HCT153E can be determined by referring to the datasheet, which provides typical and maximum values for propagation delay (tPD) under various operating conditions.
