_______________General DescriptionThe 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 (7Ωmax). They also offer low leak-
age over temperature (INO(OFF)less than 2.5nA at
+85°C) and fast switching speeds (tTRANSless 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.

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.

this data sheet.

Note 4:ΔRON= RON(MAX)- RON(MIN).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.
Note 5:Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
Note 6:Off isolation = 20log VCOM/VNO, where VCOM= output and VNO= input to off switch.

__________Applications Information
Operation with Supply Voltages
Other than ±15VUsing supply voltages other than ±15V will reduce the
analog signal range. The MAX306/MAX307 switches
operate with ±4.5V to ±20V bipolar supplies or with a
+4.5V to +30V single supply; connect V- to GND when
operating with a single supply. Also, both device types
can operate with unbalanced supplies such as +24V
and -5V. The Typical Operating Characteristicsgraphs
show typical on-resistance with 20V, 15V, 10V, and 5V
supplies. (Switching times increase by a factor of two
or more for operation at 5V.)
Overvoltage Protection Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings may cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by either
the logic inputs, NO, or COM. If power-supply
sequencing is not possible, add two small signal
diodes in series with supply pins for overvoltage pro-
tection (Figure 1). Adding diodes reduces the analog
signal range to 1V above V+ and 1V below V-, but low
switch resistance and low leakage characteristics are
unaffected. Device operation is unchanged, and the
difference between V+ and V- should not exceed +44V.
