_______________General DescriptionThe MAX308/MAX309 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 5Ωbetween
channels and remains flat over the specified analog sig-
nal range (7Ωmax). They also offer low leakage over
temperature (NO-off leakage current less than 5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX308 is a single-ended 1-of-8
device, and the MAX309 is a differential 2-of-4 device.
The MAX308/MAX309 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 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 DG408, DG409, DG508A, and DG509A.

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 3:Guaranteed by design.
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 less than ±15V will reduce the
analog signal range. The MAX308/MAX309 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. Both device types can
also 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 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 protection (Figure 1).
Adding diodes reduces the analog signal range to 1V
below V+ and 1V above V-, but does not affect the
devices’ low switch resistance and low leakage charac-
teristics. Device operation is unchanged, and the differ-
ence between V+ and V- should not exceed +44V.
