SN74HC245NSR Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HC245NSR is 50 MHz.
  • Yes, the SN74HC245NSR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
  • The enable pins (EN1 and EN2) are active-low, meaning they need to be pulled low to enable the corresponding direction of data transfer. Connect them to GND or a logic low signal to enable the device.
  • The SN74HC245NSR can sink or source up to 25 mA of current per output pin.
  • Yes, the SN74HC245NSR is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V).
