Precision, 8-Channel/Dual 4-Channel,
Low-Voltage, CMOS Analog Multiplexers
General Description
Features
The MAX398/MAX399 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ω between
channels and remains flat over the specified analog sig-
nal range (11Ω max). They also offer low leakage over
temperature (NO off-leakage current less than 2.5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX398 is an 8-channel device, and
the MAX399 is a dual 4-channel device.
♦ Pin Compatible with Industry-Standard
DG408/DG409/DG508A/DG509A
♦ Guaranteed On-Resistance Match
Between Channels (< 6Ω)
♦ Low On-Resistance (< 100Ω)
♦ Guaranteed Flat On-Resistance over Signal
Range (< 11Ω)
♦ Guaranteed Low Charge Injection (< 5pC)
♦ NO Off-Leakage Current < 1nA at +85°C
♦ COM Off-Leakage Current < 2.5nA at +85°C
♦ ESD Protection > 2000V
♦ +3V to +15V Single-Supply Operation
3V to 8V Bipolar-Supply Operation
♦ Low Power Consumption (< 300µW)
♦ Rail-to-Rail Signal Handling
The MAX398/MAX399 are fabricated with Maxim’s low-
voltage silicon-gate process. Design improvements yield
extremely low charge injection (less than 5pC) and guar-
antee electrostatic discharge protection (ESD) greater
than 2000V.
These muxes operate with a single +3V to +15V supply or
bipolar 3V to 8V supplies, while retaining CMOS-logic
input compatibility and fast switching. CMOS inputs pro-
vide reduced input loading. The MAX398/MAX399 are
pin compatible with the industry-standard DG408,
DG409, DG508A, and DG509A.
♦ TTL/CMOS-Logic Compatible

Note 1: Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
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 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges, i.e., V = 3V to 0 and 0 to -3V.
NO
Note 6: Leakage parameters are 100ꢀ tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation = 20log V / V , V = output,

Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.

Operation with Supply Voltages

V+
MAX398
MAX399
Using supply voltages less than 5V reduces the analog
signal range. The MAX398/MAX399 muxes operate with
3V to 8V bipolar supplies or with a +3V to +15V single
supply. Connect V- to GND when operating with a single
supply. Both device types can also operate with unbal-
anced supplies, such as +10V and -5V. The Typical
Operating Characteristics graphs show typical on-resis-
tance with 3V, 5V, +3V, 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 can 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 (D1, D2) in
series with supply pins for overvoltage protection
(Figure 1). Adding diodes reduces the analog signal
range to one diode drop below V+ and one diode drop
* INTERNAL PROTECTION DIODES
-5V
Figure 1. Overvoltage Protection Using External Blocking Diodes
above V-, but does not affect the devices’ low switch
resistance and low leakage characteristics. Device
operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection
diodes are not recommended when using a single supply.
