SN74HC245N Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HC245N is 50 MHz.
  • Yes, the SN74HC245N is compatible with 5V systems, but it can also operate at lower voltages down to 2V.
  • The enable pins (EN1 and EN2) are active-low, meaning they must be pulled low to enable the corresponding direction of data transfer. Tie them to VCC or use a pull-up resistor if not used.
  • The propagation delay of the SN74HC245N is approximately 10 ns (typical) at 25°C and 5V supply voltage.
  • Yes, the SN74HC245N can be used as a level shifter, but it's not its primary function. It's primarily designed as a bidirectional transceiver.
