Quadruple Bilateral Analog Switch

Quadruple Bilateral Analog Switch - SN74LV4066A


This quadruple silicon-gate CMOS analog switch is designed for 2-V to 5.5-V VCC operation.

These switches are designed to handle both analog and digital signals. Each switch permits signals with amplitudes up to 5.5 V (peak) to be transmitted in either direction.

Each switch section has its own enable-input control (C). A high-level voltage applied to C turns on the associated switch section.

Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.


  • 2-V to 5.5-V VCC Operation
  • Support Mixed-Mode Voltage Operation on All Ports
  • High On-Off Output-Voltage Ratio
  • Low Crosstalk Between Switches
  • Individual Switch Controls
  • Extremely Low Input Current
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
    • 1000-V Charged-Device Model (C101)
