CD4066BM/CD4066BC Quad Bilateral Switch
General Description
The CD4066BM/CD4066BC is a quad bilateral switch in-
tended for the transmission or multiplexing of analog or digi-
tal signals. It is pin-for-pin compatible with CD4016BM/
CD4016BC, but has a much lower ‘‘ON’’ resistance, and
‘‘ON’’ resistance is relatively constant over the input-signal
range.
