Description
The MAX4508/MAX4509 are 8-to-1 and dual 4-to-1 fault-protected multiplexers that are pin compatible with the industry-standard DG508/DG509. The MAX4508/MAX4509 operate with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. These multiplexers feature fault-protected inputs, rail-to-rail signal handling capability, and overvoltage clamping at 150mV beyond the rails.

Both parts offer ±40V overvoltage protection with supplies off and ±25V protection with supplies on. On-resistance is 400Ω max and is matched between channels to 15Ω max. All digital inputs have TTL logic thresholds, ensuring both TTL and CMOS logic compatibility when using a single +12V supply or dual ±15V supplies.

Key Features   Applications/Uses
  • ±40V Fault Protection with Power Off
    ±25V Fault Protection with ±15V Supplies
  • Rail-to-Rail Signal Handling
  • No Power-Supply Sequencing Required
  • All Channels Off with Power Off
  • Output Clamped to Appropriate Supply Voltage During Fault Condition
  • 1kΩ Output Clamp Resistance During Overvoltage
  • 400Ω max On-Resistance
  • 20ns Fault-Response Time
  • ±4.5V to ±20V Dual Supplies
    +9V to +36V Single Supply
