The recommended operating voltage range for the 74LVX238MTR is 1.65V to 3.6V, as specified in the datasheet. However, it's recommended to operate the device within the 2.3V to 3.6V range for optimal performance and to ensure compatibility with most digital systems.
It's recommended to follow a controlled power-up and power-down sequence to prevent unwanted latch-up or damage to the device. A slow and monotonic power-up sequence is recommended, with a rise time of at least 1ms. During power-down, the voltage should be reduced slowly and monotonically to prevent back-powering the device.
The maximum frequency of operation for the 74LVX238MTR is dependent on the operating voltage and load conditions. However, as a general guideline, the device can operate up to 100MHz at 3.3V and 50MHz at 2.5V, with a maximum toggle frequency of 50MHz.
To ensure signal integrity and minimize noise, it's recommended to use a low-impedance PCB design, with short signal traces and minimal stubs. Additionally, use decoupling capacitors (e.g., 0.1uF) close to the device's power pins to filter out noise and reduce electromagnetic interference (EMI).
The recommended termination scheme for the 74LVX238MTR is to use a series terminator (e.g., 33Ω) at the far end of the transmission line, with a parallel terminator (e.g., 50Ω) at the near end. This helps to minimize reflections and ensure signal integrity.
