Maxim DG407DWI Improved, 16-channel/dual 8-channel, cmos analog multiplexer Datasheet

19-4729; Rev 3; 6/99
Improved, 16-Channel/Dual 8-Channel,
CMOS Analog Multiplexers
____________________________Features
Maxim’s redesigned DG406 and DG407 CMOS analog
multiplexers now feature guaranteed matching between
channels (8Ω max) and flatness over the specified signal range (9Ω max). These low on-resistance muxes
(100Ω max) 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 DG406 is a 1 of 16 multiplexer/demultiplexer and
the DG407 is a dual 8-channel multiplexer/demultiplexer. Both muxes operate with a +4.5V to +30V single
supply and with ±4.5V to ±20V dual supplies. ESD protection 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 DG406 and DG407.

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.

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.
Using supply voltages other than ±15V reduces the
analog signal range. The DG406/DG407 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 Characteristics graphs
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 maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs and analog signals. 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
