The maximum frequency of operation for the CD54HCT574F3A is 100 MHz.
To ensure signal integrity, use a low-impedance PCB design, minimize trace lengths, and use decoupling capacitors to reduce noise and ringing.
The recommended power-on sequence is to apply VCC before applying any input signals, and to ensure that all inputs are at a valid logic level before applying VCC.
To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device at maximum power dissipation for extended periods.
The recommended layout and routing involves keeping input and output traces short and separate, using a ground plane, and avoiding vias and right-angle bends in critical signal paths.
