MAX4708

Fault-Protected, Single 8-to-1/Dual 4-to-1 Multiplexers


Please check latest availability status for a specific part variant.

Description

The MAX4708/MAX4709 8-to-1 and dual 4-to-1 fault-protected multiplexers are pin compatible with the industry-standard 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 outputs. 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 feature 400Ω (max) on-resistance with 15Ω (max) 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 logic-compatible 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.
