SN74HC240PW datasheet by Texas Instruments

SN74HC240PW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC240PW?
  The maximum operating frequency of the SN74HC240PW is 50 MHz, but it can vary depending on the output load and supply voltage.
• How do I handle the power-up and power-down sequencing of the SN74HC240PW?
  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 temperature range for the SN74HC240PW?
  The recommended operating temperature range for the SN74HC240PW is -40°C to 85°C, but it can operate up to 125°C with reduced performance.
• How do I ensure the SN74HC240PW is properly decoupled from the power supply?
  It is recommended to use a 0.1 μF ceramic capacitor between the VCC pin and GND pin, and a 10 μF electrolytic capacitor between the VCC pin and GND pin for proper decoupling.
• What is the maximum output current that the SN74HC240PW can sink or source?
  The maximum output current that the SN74HC240PW can sink or source is 25 mA per pin, but it is recommended to limit the output current to 10 mA per pin for reliable operation.
