Vishay / Siliconix DG405B Low-Power High-Speed CMOS Analog Switches

Vishay / Siliconix DG405B Low-Power High-Speed CMOS Analog Switches are monolithic analog switches replacing the popular DG405 analog switches. The DG405B Switches provide improved performance, combining high speed (ton: 100ns typical) with low power consumption, making the DG405B series ideal for portable and battery-powered applications. Built on the Vishay / Siliconix proprietary high-voltage silicon-gate process to achieve a high voltage rating and superior switch on/off performance, break-before-make is guaranteed for the SPDT configurations.

Each switch conducts equally well in both directions when on and blocks up to 30V peak-to-peak when off. The on-resistance is very flat over the full ±15V analog range. The DG405B has four switches in two SPST pairs and is available in 16-pin plastic DIP and 16-pin SOIC packages.

  • Wide dynamic range
  • Simple interfacing
  • 44V maximum supply rating
  • ±15V analog signal range
  • 23Ω on-resistance [RDS(on)]
  • Low 40pA leakage [ID(on)]
  • Fast 100ns switching (ton)
  • 30mA continuous current (any terminal)
  • TTL and CMOS compatible
  • Single supply capability
  • -40°C to +85°C operating temperature range
  • 16-pin plastic DIP or narrow SOIC package options 

Applications

  • Audio and video switching
  • Sample-and-hold circuits
  • Test equipment
  • PBX and PABX
