Operation
After proper power is applied to the component the IC is then
capable of providing digital information that is representative
of the profile of a rotating gear. No additional optimization is
needed and minimal processing circuitry is required. This ease of
use should reduce design time and incremental assembly costs for
most applications. The following output diagram is indicative of
the ICr performance for the polarity indicated in the figure at the
bottom of the page.

Output Polarity
The output of the IC will switch from low to high as the lead-
ing edge of the tooth passes the package face in the direction
indicated in the figure below. In this system configuration, the
output voltage will be high when the package is facing a tooth. If
rotation occurs in the opposite direction, the output polarity will
invert.
Power-On State Operation:
The device is guaranteed to power up in the off state (logic high
output).
