STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics
Characteristics noted under conditions of 3.0 V ≤ VDD ≤ 5.5 V, 8.0 V ≤ VPWR ≤ 28V, -40°C ≤ TC ≤ 125°C unless otherwise
noted. Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 13 V, TA = 25°C.

Notes
6. Device operational. Wetting and sustain currents are reduced. Operating the analog multiplexer below 8.0 V is not recommended.
7. Thermal considerations must be taken when operating the device above 28 V.
