The Harris CD74HC4066 and CD74HCT4066 contains four
independent digitally controlled analog switches that use
silicon-gate CMOS technology to achieve operating speeds
similar to LSTTL with the low power consumption of
standard CMOS integrated circuits.
These switches feature the characteristic linear “ON”
resistance of the metal-gate CD4066B. Each switch is
turned on by a high-level voltage on its control input.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. Incertain applications,the external load-resistorcurrent mayinclude bothVCCandsignal-line components.To avoid drawingVCCcurrent
when switch current flows into the transmission gate inputs, (terminals 1, 4, 8 and 11) the voltage drop across the bidirectional switch
must not exceed 0.6V (calculated from RONvalues shown in the DC Electrical Specifications Table). No VCCcurrent will flow through
RLif the switch current flows into terminals 2, 3, 9 and 10.
4. θJA is measured with the component mounted on an evaluation PC board in free air.
