Typical Operating Characteristics
(VCC = VL = +4.2V, C1 = 0.22µF, C2 = C3 = C4 = 1µF, C5 = 0.1µF parallel with 47µF, RL = 3k
Ω, CL = 1000pF, data rate is 250kbps,
TA = +25°C, unless otherwise noted.)

TIMING CHARACTERISTICS
(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.)
