The maximum frequency of operation for the 74HC245DB,118 is 100 MHz.
Yes, the 74HC245DB,118 is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
The enable pins (1E and 2E) are active-low, meaning they need to be connected to GND to enable the buffer. If not used, they should be tied to VCC.
The propagation delay of the 74HC245DB,118 is typically around 10 ns, but it can vary depending on the operating conditions and load capacitance.
Yes, the 74HC245DB,118 can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for reliable operation.
