ELECTRICAL CHARACTERISTICS (continued)

= 5V, V

= 14V, T

= -40°C to +125°C, unless otherwise noted. Typical values are at T

=+25°C.)

Note 1: When V

is above 28V, the wetting current is disabled to limit power dissipation, and the switch inputs are not monitored.

When V

returns, there is a 1ms blanking time before the external switches are polled.

Note 2: This current only flows during the polling active time thus the average value is much lower. For example with a polling time

of 64ms and a polling active time of 1ms the average current on an input when connected to 14V is typically 16µA x 1/64 =

0.25µA.

Note 3: Difference between VS and IN_ voltage when wetting current has dropped to 90% of its nominal value.

Note 4: Guaranteed by design.
