♦ 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 industry’s 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 are TTL and CMOS Compatible  
♦ Low-Power Monolithic CMOS Design

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.
