TYPICAL APPLICATIONS
TYPICAL TIME-DIVISION APPLICATION OF THE 4052B
Control of analog signals up to 20V peak-to-peak
can be achieved by digital signal amplitudes of 4.5

For example, if V

–13.5V, analog signals from– 13.5Vto + 4.5V can
be controlled by digital inputs of 0 to 4.5V. In certain
applications, the external load-resistor current may
include both V

and signal-line components. To
avoid drawing V
