_______________General DescriptionMaxim’s redesigned DG408 and DG409 CMOS analog
multiplexers now feature guaranteed matching between
channels (8Ωmax) and flatness over the specified sig-
nal range (9Ωmax). These low on-resistance muxes
(100Ωmax) conduct equally well in either direction and
feature guaranteed low charge injection (15pC max). In
addition, these new muxes offer low input off-leakage
current over temperature—less than 5nA at +85°C.
The DG408 is a 1-of-8 multiplexer/demultiplexer and
the DG409 is a dual 4-channel multiplexer/demultiplex-
er. Both muxes operate with a +4.5V to +30V single
supply and with ±4.5V to ±20V dual supplies. ESD pro-
tection is guaranteed to be greater than 2000V per
Method 3015.7 of MIL-STD-883. These improved
muxes are pin-compatible plug-in upgrades for the
industry standard DG408 and DG409.

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.

Note 2:The algebraic convention where the most negative value is a minimum and the most positive value a maximum is used in
this data sheet.
Note 3:Guaranteed by design.
Note 4:∆RON= 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 VD/VS, where VD= output and VS= input to off switch.

__________Applications Information
Operation with
Supply Voltages Other than 15VUsing supply voltages less than ±15V reduces the ana-
log signal range. The DG408/DG409 switches operate
with ±4.5V to ±20V bipolar supplies or with a +4.5V to
+40V single supply. Connect V- to GND when operat-
ing 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, S or D. 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.
