SN74HC240DBR datasheet by Texas Instruments

SN74HC240DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC240DBR?
  The maximum operating frequency of the SN74HC240DBR is 50 MHz, but it can vary depending on the load capacitance and the output current.
• How do I handle the power-up and power-down sequencing of the SN74HC240DBR?
  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 SN74HC240DBR?
  The recommended operating voltage range for the SN74HC240DBR is 2V to 6V, but it can operate down to 1.5V with reduced performance.
• How do I ensure the SN74HC240DBR is properly decoupled?
  It is recommended to use a 0.1uF ceramic capacitor between the VCC pin and the GND pin, and to place it as close as possible to the device to reduce noise and ensure proper operation.
• What is the maximum output current of the SN74HC240DBR?
  The maximum output current of the SN74HC240DBR is 25mA per output pin, but it can be limited by the total device power dissipation.
