_______________General Description
The MAX306/MAX307 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100
), which is matched to within 5
between channels and remains flat over the specified
analog signal range (7
max). They also offer low leak-
age over temperature (I
NO(OFF)
less than 2.5nA at
+85C) 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 +4.5V to +30V sup-
ply, 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.

On-resistance match between channels and flatness are guaranteed only with specified
voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured at
the extremes of the specified analog signal range.
