Fault-Protected, High-Voltage Single 8-to-1/
Dual 4-to-1 Multiplexers with Output Clamps
General 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 fea-
ture fault-protected inputs, rail-to-rail signal handling
capability, and overvoltage clamping at 150mV beyond
the rails.
Both parts offer ±40V overvoltage protection with sup-
plies 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 com-
patibility when using a single +12V supply or dual ±15V
supplies.
