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
±10%. MAX3237E: C1–C4 = 0.1µF tested at +3.3V ±5%, C1–C4 = 0.22µF tested at +3.3V ±10%; C1 = 0.047µF, C2, C3, C4 =
0.33µF tested at +5.0V ±10%. MAX3246E; C1-C4 = 0.22µF tested at +3.3V ±10%; C1 = 0.22µF, C2, C3, C4 = 0.54µF tested at
5.0V ±10%.
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
the supply rails.
Note 6:
Transmitter skew is measured at the transmitter zero crosspoints.
