ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions 4.5 V ≤ VDD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 27 V, -40°C ≤ TA ≤ 125°C, unless otherwise noted.

Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.

Notes

11. Output OFF Open Load Detection Current is the current required to flow through the load for the purpose of detecting the existence of

an open load condition when the specific output is commanded OFF.

12. Guaranteed by process monitoring. Not production tested.
