CD74HC540E Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the CD74HC540E is 25 MHz.
-
Yes, the CD74HC540E 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 is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
-
The propagation delay of the CD74HC540E is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
-
Yes, the CD74HC540E 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.
