The maximum operating frequency of the SN74LVC8T245DWR is 100 MHz.
Yes, the SN74LVC8T245DWR is compatible with 3.3V systems and can operate with a supply voltage range of 1.65V to 3.6V.
The direction control pins (DIR) should be tied to a valid logic level (VCC or GND) to configure the direction of data flow. Leaving them floating can cause unpredictable behavior.
The propagation delay of the SN74LVC8T245DWR is approximately 2.5 ns at 25°C and 3.3V supply voltage.
No, the SN74LVC8T245DWR is not compatible with 5V systems. It is designed to operate with a maximum supply voltage of 3.6V.
