The recommended operating voltage range for the CD74ACT280M is 4.5V to 5.5V, as specified in the datasheet. However, it's essential to note that the device can tolerate a voltage range of 3.5V to 7V, but the performance may vary.
To handle thermal considerations, ensure that the device is mounted on a PCB with a thermal pad connected to a ground plane or a heat sink. This helps to dissipate heat efficiently. Additionally, follow the recommended layout and thermal design guidelines provided in the datasheet.
The maximum clock frequency supported by the CD74ACT280M is 100 MHz. However, this frequency may vary depending on the system design, capacitive loading, and other factors. It's recommended to consult the datasheet and perform simulations to determine the optimal clock frequency for your specific application.
To ensure signal integrity, follow proper PCB design practices, such as using controlled impedance traces, minimizing signal routing, and using termination resistors as needed. Additionally, use a low-skew clock distribution network and ensure that the clock signal is clean and stable.
The recommended input rise and fall time for the CD74ACT280M is 2 ns or less. This ensures that the device can accurately detect the input signals and maintain proper operation.
