The 74VHC4066 is a quad analog switch with low on-resistance and low off-leakage. It is a bidirectional switch, so any analog input can be used as an output and vice versa.
The document describes the 74VHC4066 as a digitally controlled analog switch utilizing advanced silicon-gate CMOS technology. Key features include low on-resistance (30 ohms typical), low off-leakage, and bidirectional operation allowing up to 12V peak analog signals with digital control of the same range.
The datasheet provides absolute maximum ratings, DC and AC electrical characteristics across various supply voltages (2.0V to 12.0V), switching time waveforms, test circuits for crosstalk and distortion, and physical dimensions for three available packages: SOIC, TSSOP, and PDIP.
| Typical switch enable time | 15 ns |
|---|---|
| Wide analog input voltage range | 0-12V |
| Low on resistance (typical) | 30 ohms |
| Maximum quiescent current | 80 uA |
The devices allow control of up to 12V peak analog signals.
Yes, they are bidirectional switches where any analog input may be used as an output and vice-versa.
