Note:
Because of the ultra-high speed of the PY264, 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_CC and ground planes
directly up to the contactor fingers. A 0.01 µF high frequency capacitor
is also required between V_CC and ground.
