* including scope and test fixture.

Note:

Because of the ultra-high speed of the P4C168, P4C169 AND P4C170

care must be taken when testing these devices; 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

AC TEST CONDITIONS

high frequency capacitor is also required between V

CC and ground. To

avoid signal reflections, proper termination must be used; for example,

a 50

Ω test environment should be terminated into a 50Ω load with 1.73V

(Thevenin Voltage) at the comparator input, and a 116

Ω resistor must be

used in series with D

OUT to match 166Ω (Thevenin Resistance).
