Precision, 16-Channel/Dual 8-Channel,
High-Performance, CMOS Analog Multiplexers
General Description
The MAX306/MAX307 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100Ω), which is matched to within 5Ω
between channels and remains flat over the specified
analog signal range (7Ω, max). They also offer low leak-
age over temperature (I
NO(OFF)
less than 2.5nA at
+85°C) and fast switching speeds (t
TRANS
less than
250ns). The MAX306 is a single-ended 1-of-16 device,
and the MAX307 is a differential 2-of-8 device.
The MAX306/MAX307 are fabricated with Maxim’s
improved 44V silicon-gate process. Design improve-
ments yield extremely low charge injection (less than
10pC) and guarantee electrostatic discharge (ESD)
protection greater than 2000V.
These muxes operate with a single +5V to +30V supply,
or bipolar ±4.5V to ±20V supplies, while retaining
TTL/CMOS-logic input compatibility and fast switching.
CMOS inputs provide reduced input loading. These
improved parts are plug-in upgrades for the industry-
standard DG406, DG407, DG506A, and DG507A.

Signals on NO, COM, A0, A1, A2, A3, or EN 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.
