Precision, 8-Channel/Dual 4-Channel,
Low-Voltage, CMOS Analog Multiplexers
General Description
The MAX398/MAX399 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ω between
channels and remains flat over the specified analog sig-
nal range (11Ω max). They also offer low leakage over
temperature (NO off-leakage current less than 2.5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX398 is an 8-channel device, and
the MAX399 is a dual 4-channel device.
The MAX398/MAX399 are fabricated with Maxim’s low-
voltage silicon-gate process. Design improvements yield
extremely low charge injection (less than 5pC) and guar-
antee electrostatic discharge protection (ESD) greater
than 2000V.
These muxes operate with a single +3V to +15V supply or
bipolar ±3V to ±8V supplies, while retaining CMOS-logic
input compatibility and fast switching. CMOS inputs pro-
vide reduced input loading. The MAX398/MAX399 are
pin compatible with the industry-standard DG408,
DG409, DG508A, and DG509A.

Note 1:
Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
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.
