TIMING CHARACTERISTICS—MAX3237E
(VCC = +3V to +5.5V, C1–C4 = 0.1F, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 3)
Note 3: MAX3222E/MAX3232E/MAX3241E: C1–C4 = 0.1F tested at +3.3V ±10%; C1 = 0.047F, C2, C3, C4 = 0.33F tested at +5.0V
±10%. MAX3237E: C1–C4 = 0.1F tested at +3.3V ±5%, C1–C4 = 0.22F tested at +3.3V ±10%; C1 = 0.047F, C2, C3, C4 =
0.33F tested at +5.0V ±10%. MAX3246E: C1-C4 = 0.22F tested at +3.3V ±10%; C1 = 0.22F, C2, C3, C4 = 0.54F 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: MAX3241EEUI is specified at TA = +25°C.
Transmitter skew is measured at the transmitter zero crosspoints.
