±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V,
Note 2: MAX3222E/MAX3232E/MAX3241E: C1–C4 = 0.1µF tested at 3.3V ±10%; C1 = 0.047µF, C2–C4 = 0.33µF tested at 5.0V
Note 3: The MAX3237E logic inputs have an active positive feedback resistor. The input current goes to zero when the inputs are at
Note 4: Transmitter skew is measured at the transmitter zero crosspoints.
