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

to 20V (if VDD –VSS = 3V, a VDD –VEE of up to 13V

can be controlled ; for VDD –VEE level differences

above 13V, a VDD –VSS of at least 4.5V is required).

For example, if VDD = + 5V, VSS = 0, and VEE =

–13.5V, analog signals from – 13.5V to + 4.5V can

be controlled by digital inputs of 0 to 4.5V. In certain

applications, the external load-resistor current may

include both VDD and signal-line components. To

avoid drawing VDD current when switch current

flows into the transmission gate inputs, the voltage

drop across the bidirectional switch must not exceed

0,8 volt (valvulated from RON values shown in

ELECTRICAL CHARACTERISTICS CHART). No

VDD current will flow through RL if the switch current

flows into lead 3 on the HCC/HCF4051 ; leads 3 and

13 on the HCC/HCF4052 ; leads 4, 14, and 15 on

the HCC/HCF4053.
