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 faultprotected multiplexers that are pin compatible with the i n d u s t r y - s t a n d a r d 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. Onr e s i s t a n c e is 400 m a x and is matched between channels to 15 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.
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 1k Output Clamp Resistance During Overvoltage o 400 max On-Resistance o 20ns Fault-Response Time o ±4.5V to ±20V Dual Supplies +9V to +36V Single Supply o TTL/CMOS-Compatible Logic Inputs

Note 1: COM_, EN, and A_ pins are not fault protected. Signals on COM_, EN, or A_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
