CD4066BC
Quad Bilateral Switch
General Description
The CD4066BC is a quad bilateral switch intended for the
transmission or multiplexing of analog or digital signals. It is
pin-for-pin compatible with CD4016BC, but has a much
lower “ON” resistance, and “ON” resistance is relatively
constant over the input-signal range.

“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be operated at these limits. The tables of “Recom-
mended Operating Conditions” and “Electrical Characteristics” provide con-
ditions for actual device operation.

Note 3:
AC Parameters are guaranteed by DC correlated testing.
Note 4:
These devices should not be connected to circuits with the power “ON”.
Note 5:
In all cases, there is approximately 5 pF of probe and jig capacitance in the output; however, this capacitance is included in C

Special Considerations
In applications where separate power sources are used to
drive V
DD
and the signal input, the V
DD
current capability
should exceed V
DD
/R
L
(R
L
=
effective external load of the 4
CD4066BC bilateral switches). This provision avoids any
permanent current flow or clamp action of the V
DD
supply
when power is applied or removed from CD4066BC.
In certain applications, the external load-resistor current
may include both V
DD
and signal-line components. To
avoid drawing V
DD
current when switch current flows into
terminals 1, 4, 8 or 11, the voltage drop across the
bidirectional switch must not exceed 0.6V at T
A
≤
25
°
C, or
0.4V at T
A
>
25
°
C (calculated from R
ON
values shown).
No V
DD
current will flow through R
L
if the switch current
flows into terminals 2, 3, 9 or 10.
