16-channel analog multiplexer/demultiplexer
[1] t
pd
is the same as t
PHL
and t
PLH
.
[2] Due to higher Z terminal capacitance (16 switches versus 1) the delay figures to the Z terminal are higher than those to the Y terminal.
[3] t
on
is the same as t
PHZ
and t
PLZ
.
[4] t
off
is the same as t
PZH and
t
PZL
.
