The recommended operating voltage range for the SN74LVCR2245APWRE4 is 2.3V to 3.6V, as specified in the datasheet. However, it's recommended to operate the device at a fixed voltage of 3.3V or 2.5V for optimal performance.
To ensure signal integrity, it's essential to follow proper PCB design and layout guidelines, such as using controlled impedance traces, minimizing trace lengths, and adding termination resistors as needed. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
While the SN74LVCR2245APWRE4 is designed for low-voltage applications, it's not recommended to use it in a 5V system. The device is not rated for 5V operation, and exceeding the recommended voltage range may cause damage or affect its performance and reliability.
When using the SN74LVCR2245APWRE4 in a system with multiple power domains, it's essential to ensure proper power sequencing to prevent damage or latch-up. TI recommends following a specific power-up sequence, as outlined in the datasheet, to ensure safe and reliable operation.
The SN74LVCR2245APWRE4 supports clock frequencies up to 250 MHz, making it suitable for high-speed applications. However, the actual clock frequency limit may depend on the specific application, PCB design, and signal integrity considerations.
