pulse for IC(on) = 2 mA

NOTES: A. The input waveform is supplied by a generator with the following characteristics: ZOUT = 50 Ω, tr ≤ 15 ns, duty cycle ≈ 1%,

tw = 100 µs.

B. The output waveform is monitored on a oscilloscope with the following characteristic: tr ≤ 12 ns, Rin ≥ 1 MΩ, Cin ≤ 20 pF.
