Note:
Because of the ultra-high speed of the P4C188/L, 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
and ground
planes directly up to the contactor fingers. A 0.01 μF high frequency
capacitor is also required between V
and ground. To avoid signal
reflections, proper termination must be used; for example, a 50
test
environment should be terminated into a 50
load with 1.73V (Thevenin
Voltage) at the comparator input, and a 116
resistor must be used in
series with D
OUT
to match 166
(Thevenin Resistance).
