AC TEST CONDITIONS
* including scope and test fixture.
Note:
Due to the ultra-high speed of the P4C150, care must be taken when testing
this device; an inadequate setup can cause a normal functioning part to be
rejected as faulty. Long high-inductance leads that cause supply bounce
must be avoided by bringing the V
contactor fingers. A 0.01 µF high frequency capacitor is also required
