The CD74HC564E can operate at frequencies up to 25 MHz.
The CD74HC564E requires a single power supply voltage (VCC) of 2.0 to 6.0 volts, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
The propagation delay time (tPD) for the CD74HC564E is typically around 10-15 ns, but can vary depending on the operating conditions and load capacitance.
Yes, the CD74HC564E is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range (Vih = 2.0V, Vil = 0.8V) to ensure proper operation.
The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (GND) and disabled when OE is high (VCC).
