1. VIN = input pulse and has the following characteristics:
PRR ≤ 1 MHz, t1 = t0 ≤ 2.5 ns.
2. Inputs not under test are at ground.
3 CL = 50 Pf ±10%, including scope probe, wiring, and stray capacitance
without package in test fixture.
4 R1 = R2 = 499Ω ±1%.
5 Voltage measurements are to be made with respect to network ground terminal.
