Overview

19-1414; Rev 0; 1/99 Fault-Protected, High-Voltage Single 8-to-1/Dual 4-to-1 Multiplexers General Description The MAX4508/MAX4509 are 8-to-1 and dual 4-to-1 faultprotected 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.
Onresistance is 400 Ω max and is matched between channels to 15Ωmax.
All digital inputs have TTL logic thresholds, ensuring both TTL and CMOS logic compatibility when using a single +12V supply or dual ±15V supplies.
Features o ±40V Fault Protection with Power Off ±25V Fault Protection with ±15V Supplies o Rail-to-Rail Signal Handling o No Power-Supply Sequencing Required o All Channels Off with Power Off o Output Clamped to Appropriate Supply Voltage During Fault Condition o 1kΩ Output Clamp Resistance During Overvoltage o 400Ω max On-Resistance o 20ns Fault-Response Time o ±4.
