2-channel analog multiplexer/demultiplexer

11.2 Additional dynamic characteristics

Test data is given in Table 11.

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.
