MAX3222E/MAX3232E/MAX3241E: C1–C4 = 0.1μF tested at 3.3V ±10%; C1 = 0.047μF, C2–C4 = 0.33μF tested at 5.0V
±10%. MAX3237E: C1–C4 = 0.1μF, tested at 3.3V ±5%; C1–C4 = 0.22μF tested at 3.3V ±10%; C1 = 0.047μF, C2–C4 =
0.33μF tested at 5.0V ±10%.
Note 3:
The MAX3237E logic inputs have an active positive feedback resistor. The input current goes to zero when the inputs are at
the supply rails.
Note 4:
Transmitter skew is measured at the transmitter zero crosspoints.
