Test Circuit for Electrical Characteristics(1-5)

Notes:

CL = Load capacitance: includes jig and probe capacitance.

RT = Termination resistance: should be equal to ZOUT of the Pulse Generator

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

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

All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.

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