+2.35V to +5.5V, 1µA, 2Tx/2Rx RS-232 Transceivers
with ±15kV ESD-Protected I/O and Logic Pins
ELECTRICAL CHARACTERISTICS (continued)
(VCC = +2.35V to +5.5V, VL = +1.65V to +5.5V. When VCC < +4.5V, C1 = C2 = C3 = C4 = 0.1µF; when VCC ≥ +4.5V, C1 = 0.047µF,
C2 = C3 = C4 = 0.33µF; TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = VL = +3.3V, TA = +25°C.)
