The maximum operating frequency of the TXB0101 is 100 MHz. However, it's recommended to check the propagation delay and signal integrity for high-frequency applications.
In a bidirectional bus, the direction control pin (DIR) should be controlled by the master device. The DIR pin should be set to high for data transmission from A to B and low for data transmission from B to A.
The recommended termination scheme for the TXB0101 is to use a series resistor (Rs) at the output of the driver and a parallel resistor (Rt) at the receiver end. The values of Rs and Rt depend on the specific application and signal integrity requirements.
No, the TXB0101 is not recommended for use as a level shifter for voltages above 3.6V. The maximum voltage rating for the VCCA and VCCB pins is 3.6V. Using the device with higher voltages may cause damage or affect its performance.
To ensure signal integrity with the TXB0101, it's recommended to follow proper PCB design practices, such as using controlled impedance traces, minimizing trace length and stubs, and using signal termination resistors. Additionally, the device's output should be AC-coupled to the receiver to prevent DC voltage differences.
