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. * All voltage values are referred to VSS pin voltage. 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 switch is ON or to VSS when the switch is OFF. This 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. HCC/HCF4066B 2/11 |
