Note 1: Normal—Does not affect laser power.
Note 2: Supply-shorted current is assumed to be primarily on the circuit board (outside this device), and the main supply is col-
lapsed by the short.
Note 3: Normal in functionality, but performance could be affected.
Warning: Shorted to V CC or shorted to ground on some pins can violate the Absolute Maximum Ratings .
