SWITCHING TIME TEST CIRCUIT AND WAVEFORMS @ 25°C

NOTE:

tsetup is the minimum time before the positive

transition of the clock pulse (C) that information must

be present at the input D or S.

thold is the minimum time after the positive tranĆ

sition of the clock pulse (C) that information must

remain unchanged at the input D or S.

50Ćohm termination to ground loĆ

cated in each scope channel input.

All input and output cables to the

scope are equal lengths of 50Ćohm

coaxial cable. Wire length should be

< 1/4 inch from TPin to input pin and

TPout to output pin.

Unused outputs are connected to a

50Ćohm resistor to ground.
