Unless otherwise noted, the following conditions apply:PVCC = VCC = 3.3V for the LTM2889-3, PVCC = VCC = 5V for the LTM2889-5, VL = 3.3V, GND = GND2 = S = RE = RS = 0V, ON = VL.Figure 10 applies for VCC2 = 3.3V; otherwise ADJ is floating. Figure 1 applies with RL = 60Ω and dominant mode measurements aretaken prior to TXD dominant timeout (t < tTOTXD).
