♦ 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.
