Fault-Protected, Single 8-to-1/ Dual 4-to-1 Multiplexers
General Description
The MAX4708/MAX4709 8-to-1 and dual 4-to-1 fault-protected multiplexers are pin compatible with the industrystandard DG508/DG509. The MAX4708/MAX4709 are similar to the MAX4508/MAX4509, but these devices do not have clamp diodes to the supply rails on the switch o u t p u t s . These multiplexers feature fault-protected inputs, Rail-to-Rail® signal-handling capability, and do not require power-supply sequencing. Both devices offer ±40V overvoltage protection with the supplies off, ±36V protection with the supplies on, and f e a t u r e 400 ( m a x ) on-resistance with 15 ( m a x ) matching between channels. The MAX4708/MAX4709 operate with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. All digital inputs have TTL logiccompatible thresholds, ensuring both TTL and CMOS logic compatibility when using a single +12V supply or dual ±15V supplies. For low-voltage applications requiring fault protection, refer to the MAX4711/MAX4712/MAX4713 data sheet. o All Channels Off with Power Off o Rail-to-Rail Signal Handling o 400 (max) On-Resistance o ±40V Fault Protection with Power Off o ±25V Fault Protection with ±15V Supplies o 100ns Fault-Response Time o ±4.5V to ±20V Dual Supplies o +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.
