Analog Multiplexer Single 8:1 16-Pin PDIP N

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 400O (max) on-resistance with 15O (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.
