CD74HCT240EE4 datasheet by Texas Instruments

CD74HCT240EE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of CD74HCT240EE4?
  The maximum operating frequency of CD74HCT240EE4 is 25 MHz, but it can vary depending on the system design and capacitive loading.
• How do I handle the power-up and power-down sequencing of CD74HCT240EE4?
  It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted output states.
• What is the recommended termination scheme for CD74HCT240EE4?
  A series termination of 33 ohms to 50 ohms is recommended to reduce signal reflections and improve signal integrity.
• Can I use CD74HCT240EE4 in a 5V system?
  Yes, CD74HCT240EE4 is compatible with 5V systems, but the input voltage should not exceed 5.5V to prevent damage to the device.
• How do I handle the thermal management of CD74HCT240EE4?
  The device should be mounted on a PCB with a thermal pad connected to a ground plane to dissipate heat. A heat sink may be required for high-power applications.
