_______________General Description
The MAX382/MAX384 are low-voltage, CMOS, 1-of-8
and dual 4-channel muxes with latchable digital inputs.
They feature low-voltage operation from a +2.7V to
+16.5V single supply and from ±3V to ±8V dual supplies. Pin compatible with the DG428/DG429, these
muxes offer low on-resistance (100Ω max) matched to
within 4Ω max between channels. Additional features
include off leakage less than 2.5nA at +85°C and guaranteed low charge injection (10pC max). ESD protection is greater than 2000V per Method 3015.7.

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.
