Note:

Because of the ultra-high speed of the PY291A, 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

planes directly up to the contactor fingers. A 0.01 µF high frequency

capacitor is also required between V
