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-pro-
tected 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.
