SN74HCT240DWRE4 datasheet by Texas Instruments

SN74HCT240DWRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT240DWRE4?
  The maximum operating frequency of the SN74HCT240DWRE4 is 50 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the SN74HCT240DWRE4?
  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 operating voltage range for the SN74HCT240DWRE4?
  The recommended operating voltage range for the SN74HCT240DWRE4 is 4.5V to 5.5V, but it can operate down to 4V with reduced performance.
• How do I ensure the SN74HCT240DWRE4 is properly decoupled?
  It is recommended to use a 0.1uF ceramic capacitor between the VCC pin and GND pin, and to place the capacitor as close to the device as possible to ensure proper decoupling.
• What is the maximum output current of the SN74HCT240DWRE4?
  The maximum output current of the SN74HCT240DWRE4 is 25mA per output pin, but it is recommended to limit the output current to 10mA per pin to ensure reliable operation.
