+3.0V to+5.5V, 1µA, RS-232/RS-485/422
Multiprotocol Transceivers
ELECTRICAL CHARACTERISTICS (continued)
(V_CC = +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%;
T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.)
