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 VCC and ground  
planes directly up to the contactor fingers. A 0.01 µF high frequency  
capacitor is also required between VCC and ground.
