_______________________________________________________________________________________
Note 2: All devices are 100% production tested at TA = +85°C. Specifications are over -40°C to +85°C and are guaranteed by design.
Note 3: Both receivers will operate over the ±70V input range. The input resistance increases with input voltage. The input resistance
will increase within 24V
≤ |VR_IN| ≤ 32V.
Note 4: Guaranteed by design, not production tested.
Note 5: Transmitter skew is measured at the transmitter zero crosspoints.
Note 6: Output recovery time is the delayed time for the transmitter to enter normal operating mode after an overvoltage condition.
TIMING CHARACTERISTICS
(VCC = +3.0V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +3.3V, TA = +25°C, unless other-
wise noted. For VCC = +3.0V to +3.6V, C1 = C2 = C3 = 0.1F, C4 = 1F. For VCC = +4.5V to +5.5V, C1 = 47nF, C2 = C3 = 330nF,
C4 = 1F.) (Note 2)
