2-channel analog multiplexer/demultiplexer

14. Additional dynamic characteristics

Test data is given in Table 12.

Deﬁnitions test circuit:

RT = termination resistance (should be equal to output impedance Zo of the pulse generator).

CL = load capacitance (including jig and probe capacitance).

RL = load resistance.

VEXT = external voltage for measuring switching times.
