5 Parameter Measurement Information

Figure 5-1.

A.

CL includes probe and jig capacitance.

B.

Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.

Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.

C.

All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr ≤ 3 ns,

tf ≤ 3 ns.

D.

The outputs are measured one at a time, with one input transition per measurement.

E.

tPLZ and tPHZ are the same as tdis.

F.

tPZL and tPZH are the same as ten.

G.

tPHL and tPLH are the same as tpd.

H.

All parameters and waveforms are not applicable to all devices.
