Key Features

  • Quad SPST configuration with four independent analog switches in a single 14-pin SOIC package
  • 40dB nominal off-state isolation ensuring minimal signal leakage when switches are open
  • 6Ω nominal on-resistance matching across channels for balanced signal routing in multiplexed systems
  • Low-voltage CMOS compatible control inputs supporting 1.65V to 5.5V digital logic levels
  • Bidirectional signal switching capability for both analog and digital signal routing applications

Applications

The SN74LV4066ADG4 is suitable for audio signal routing, data acquisition multiplexing, and general-purpose analog switching in consumer electronics and industrial control systems. It is commonly used to switch sensor signals, audio channels, and reference voltages in mixed-signal PCB designs where multiple analog paths must be independently controlled by digital logic. Its 40dB isolation and matched on-resistance also make it valuable in test and measurement equipment requiring accurate, low-crosstalk signal switching.
