Maxim Integrated 

±15kV ESD-Protected, +3.0V to +5.5V, 10nA,

RS-232/RS-485/RS-422 Multiprotocol Transceivers

ELECTRICAL CHARACTERISTICS (continued)

(VCC = +3V to +5.5V, C1–C4 = 0.1µF when tested at +3.3V ±10%; C1 = 0.047µF and C2, C3, C4 = 0.33µF when tested at +5V±10%;

TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = +3.3V and TA = +25°C.) (Note 2)
