onsemi MC74HC4066A Quad Analog Switch/Mux/Demux

onsemi MC74HC4066A Quad Analog Switch/Mux/Demux achieves fast propagation delays, low ON-resistance, and low OFF-channel leakage current by utilizing silicon-gate CMOS technology. The onsemi MC74HC4066A bilateral switch/multiplexer/demultiplexer controls digital and analog voltages that may vary across the full power-supply range (from VCC to GND).

Features

  • Fast switching and propagation speeds
  • High ON/OFF output voltage ratio
  • Low crosstalk between switches
  • Diode protection on all inputs/outputs
  • Wide power-supply voltage range (VCC - GND) = 2.0V to 12.0V
  • Analog input voltage range (VCC - GND) = 2.0V to 12.0V
  • Improved linearity and lower ON resistance over input voltage than the MC14016 or MC14066
  • Low noise
  • Chip complexity: 44 FETs or 11 equivalent gates
  • These devices are Pb-Free, halogen-free, and are RoHS compliant
  • -Q suffix for automotive and other applications requiring unique site and control change requirements; AEC-Q100 Qualified and PPAP capable
