ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of the device may be impaired.

Note 4: All digital inputs driven rail-to-rail. When driving digital inputs with

0V and 5V levels, the shutdown current will increase to 3.5mA (typ).

Note 5: Each digital input includes a small positive or negative current

The table shows the current due to this source when the input is driven at

the supply voltage opposite from the float potential. Pins CS/HOLD, F3, F2,

voltage. See “Floatable Digital Inputs” in Applications Information section.
