CD74HC243M Frequently Asked Questions (FAQ)
-
The maximum frequency of operation for the CD74HC243M is 25 MHz.
-
Yes, the CD74HC243M 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. When OE is high, the outputs are in a high-impedance state.
-
The propagation delay of the CD74HC243M is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
-
Yes, the CD74HC243M is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. Ensure that the input signals are also 3.3V-compatible.
