Note 6: MAX3241EEUI is specified at T
Note 7: Transmitter skew is measured at the transmitter zero crosspoints.
Note 3: MAX3222E/MAX3232E/MAX3241E: C1–C4 = 0.1µF tested at +3.3V ±10%; C1 = 0.047µF, C2, C3, C4 = 0.33µF tested at +5.0V
Note 4: MAX3246E devices are production tested at +25°C. All limits are guaranteed by design over the operating temperature range.
Note 5: The MAX3237E logic inputs have an active positive feedback resistor. The input current goes to zero when the inputs are at
