±70V Fault-Protected, 3.0V to 5.5V,
2Tx/2Rx RS-232 Transceiver
ELECTRICAL CHARACTERISTICS (continued)
(V_CC = +3.0V to +5.5V, T_A = -40°C to +85°C, unless otherwise noted. Typical values are at V_CC = +3.3V, T_A = +25°C, unless otherwise
noted. For V_CC = +3.0V to +3.6V, C1–C3 = 0.1µF, C4 = 1µF. For V_CC = +4.5V to +5.5V, C1 = 47nF, C2–C3 = 330nF, C4 = 1µF.) (Note 2)
