Maxim Integrated 

Low-Voltage, High-Isolation,

Dual 2-Channel RF/Video Multiplexer

ELECTRICAL CHARACTERISTICS—Dual Supplies (continued)

(V+ = VL = +4.5V to +5.5V, V- = -4.5V to -5.5V, VINH = +2.4V, VINL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical val-

ues are at TA = +25°C, V+ = VL = +5V, V- = -5V.) (Note 2)
