NOTES:
1. Use decoupling capacitors of O.lffF and 25~F from GND to Vcc, and O.01~F and 25~F from GND to VEE (0.01 and O.lffF capacitors
should be NPO Ceramic or MLC type). Decoupling capacitors should be placed as close as physically possible to the DUT and lead
length should be kept to less than l/4 inch (6mm).
2. All unused inputs should be connected to either HIGH or LOW state consistent with the LOGIC function required.
3. All unused outputs are loaded with 50 I to GND.
4. Li and L2 are equal length sol impedance lines. L3, the distance from the DUT pin to the junction of the cable from the Pulse
Generator and the cable to the Scope, should not exceed l/4 inch (6mm).
5. RT = so I terminator internal to Scope.
6. The unmatched wire stub between coaxial cable and pins under test must be less than l/4 inch (6mm) long for proper test.
7. CL = Fixture and stray capacitance " 3pF.
8. Any unterminated stubs connected anywhere along the transmission line between the Pulse Generator and the DUT or between the
DUT and the Scope should not exceed l/4 inch (6mm) in length (refer to section on AC setup procedure).
9. All so l resistors should have tolerance of+ 1% or better.
10. Test procedures are shown for only one input or set of input conditions. Other inputs are tested in the same manner.
