The maximum operating frequency of the SN74LVTH182646APM is 100 MHz.
To ensure signal integrity, use controlled impedance traces, minimize trace lengths, and use termination resistors as needed. Also, follow the recommended layout guidelines in the datasheet.
Yes, the SN74LVTH182646APM is compatible with 3.3V systems. However, ensure that the input voltage does not exceed the recommended maximum rating of 4.6V.
Power sequencing is not critical for the SN74LVTH182646APM, but it's recommended to power up the device after the power supply has stabilized to prevent latch-up.
The recommended termination scheme is to use a series terminator (Rs) of 22-33 ohms at the far end of the transmission line, and a parallel terminator (Rt) of 50-60 ohms at the near end.
