ELECTRICAL CHARACTERISTICS (continued)
(VCC = +3.0V to +5.5V, C1–C4 = 0.1F (tested at 3.3V ±5%), C1–C4 = 0.22F (tested at 3.3V ±10%), C1 = 0.047F, and
C2–C4 = 0.33F (tested at 5.0V ±10%), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
Note 2: The transmitter inputs have an active positive feedback resistor. The input current goes to zero when the inputs are at the
supply rails.
Note 3: During AutoShutdown only, a transmitter/receiver edge is defined as a transition through the transmitter/receiver input logic
wake-up thresholds.
