Table 4. Static Electrical Characteristics

Characteristics noted under conditions of 3.0V ≤ VDD ≤ 5.5V, 8.0V ≤ VPWR ≤ 28V, -40°C ≤ TC ≤ 125°C, unless otherwise

noted. Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 13V, TA = 25°C.

Notes

7. Device operational. Wetting and sustain currents are reduced. Operating the analog multiplexer below 8.0V is not recommended.

8. Thermal considerations must be taken when operating the device above 28V.
