The maximum operating frequency of the SN74AC241DW is 100 MHz.
Yes, the SN74AC241DW is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
The output enable (OE) pin should be connected to GND or VCC to enable the outputs. Leaving it unconnected or floating can cause unpredictable behavior.
The SN74AC241DW can sink or source up to 24 mA of current per output pin.
Yes, the SN74AC241DW is compatible with 3.3V systems, but the output voltage levels may not be as high as in a 5V system.
