ELECTRICAL CHARACTERISTICS The
l
denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. 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 are taken prior to TXD dominant timeout (t < tTOTXD).
