Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections

of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.

pin compatible with HCC/HCF4016B, but exhibits a

much lower ON resistance. In addition, the ON re-

sistance is relatively constant over the full input-sig-

nal range. The HCC/HCF4066B consists of four

independent bilateral switches. A single control sig-

nal is required per switch. Both the p and the n de-

vice in a given switch are biased ON or OFF

simultaneously by the control signal. As shown in

schematic diagram, the well of the n-channel device

on each switch is either tied to the input when the

configuration eliminates the variation of the switch-

transistor threshold voltage with input signal, and

thus keeps the ON resistance low over the full oper-

ating-signal range. The advantages over single-

channel switches include peak input signal voltage

swings equal to the full supply voltage, and more

constant ON impedance over the input-signal

range. For sample-and-hold applications, however,

the HCC/HCF4016B is recommended.
