Fault Input Voltage ±75V with Power Supplies Off  
Fault Input Voltage ±60V with ±15V Power Supplies  
All Switches Off with Power Supplies Off  
The MAX378 8-channel single-ended (1-of-8) multiplexer  
and the MAX379 4-channel differential (2-of-8) multiplexer  
use a series N-channel/P-channel/N-channel structure to  
provide significant fault protection. If the power supplies to  
the MAX378/MAX379 are inadvertently turned off while  
input voltages are still applied, all channels in the muxes  
are turned off, and only a few nanoamperes of leakage cur-  
rent will flow into the inputs. This protects not only the  
MAX378/MAX379 and the circuitry they drive, but also the  
sensors or signal sources that drive the muxes.  
On Channel Turns OFF if Overvoltage Occurs on  
Input or Output  
Only Nanoamperes of Input Current Under All  
Fault Conditions  
No Increase in Supply Currents Due to Fault  
Conditions  
Latchup-Proof Construction  
The series N-channel/P-channel/N-channel protection  
structure has two significant advantages over the simple  
current-limiting protection scheme of the industrys first-  
generation fault-protected muxes. First, the Maxim protec-  
tion scheme limits fault currents to nanoamp leakage  
values rather than many milliamperes. This prevents dam-  
age to sensors or other sensitive signal sources. Second,  
the MAX378/MAX379 fault-protected muxes can withstand  
a continuous ±60V input, unlike the first generation, which  
had a continuous ±35V input limitation imposed by power  
dissipation considerations.  
Operates from ±4.5V to ±18V Supplies

All digital inputs have logic thresholds of 0.8V and 2.4V,  
ensuring both TTL and CMOS compatibility without requir-  
ing pull-up resistors. Break-before-make operation is  
guaranteed. Power dissipation is less than 2mW.
