+3.0V to+5.5V, 1µA, RS-232/RS-485/422
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 TA = +25°C.)

Typical Operating Characteristics
(VCC = +3.3V, 250kbps data rate, 0.1µF capacitors, all RS-232 transmitters (RS-232 mode) loaded with 3kΩ to ground, TA = +25°C,
unless otherwise noted.)
