TIMING CHARACTERISTICS—MAX3221E/MAX3223E/MAX3243E
(VCC = +3.0V to +5.5V, C1–C4 = 0.1F (Note 2), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
Note 2: C1–C4 = 0.1F, tested at 3.3V ±10%. C1 = 0.047F, C2–C4 = 0.33F, tested at 5.0V ±10%.
Note 3: Transmitter skew is measured at the transmitter zero cross points.
