74VHC4066 Quad Analog Switch
General Description
These devices are digitally controlled analog switches utilizing advanced silicon-gate CMOS technology. These switches have low “on” resistance and low “off” leakages. They are bidirectional switches, thus any analog input may be used as an output and visa-versa. Also the 4066 switches contain linearization circuitry which lowers the “on” resistance and increases switch linearity. The 4066 devices allow control of up to 12V (peak) analog signals with digital control signals of the same range. Each switch has its own control input which disables each switch when low. All analog inputs and outputs and digital inputs are protected from electrostatic damage by diodes to VCC and ground.

Note 4: For a power supply of 5V ± 10% the worst case on resistance (RON) occurs for VHC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current occurs for CMOS at the higher voltage and so the 5.5V values should be used. Note 5: At supply voltages (VCC – GND) approaching 2V the analog switch on resistance becomes extremely non-linear. Therefore it is recommended that these devices be used to transmit digital only when using these supply voltages.
