High input enable receive mode, which disables the outputs of DP and DN, and the buffer goes into high-z state. O Differential Receiver Output (CMOS level digital output) When DP > DN, the output is H. When DP < DN, the output is L. When both DP and DN are L, the output is not guaranteed. this pin also outputs correctly regardless of the OEN input. O Schmitt Hysteresis Receiver Output for DP (D+) input (CMOS level digital output) When DP is high level, RSHP is high. When DP is low level, RSHP is low this pin also outputs correctly regardless of the OEN input. O Schmitt Hysteresis Receiver Output for DN (D-) input (CMOS level digital output) When DN is high le...
