CD74HCT240PWR datasheet by Texas Instruments

CD74HCT240PWR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of CD74HCT240PWR?
  The maximum operating frequency of CD74HCT240PWR is 50 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 CD74HCT240PWR?
  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 CD74HCT240PWR?
  A series termination scheme with a 33-ohm resistor and a 10-pF capacitor is recommended to reduce signal reflections and improve signal integrity.
• Can I use CD74HCT240PWR in a 5V system?
  Yes, CD74HCT240PWR is compatible with 5V systems, but the output voltage will be limited to the VCC voltage, which is typically 4.5V for a 5V system.
• How do I handle the thermal management of CD74HCT240PWR?
  The device should be mounted on a PCB with a thermal pad connected to a ground plane or a heat sink to dissipate heat. The maximum junction temperature is 150°C.
