MAX309
Precision, 8-Channel/Dual 4-Channel, High-Performance, CMOS Analog Multiplexers
_______________General Description
The 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 +5V to +30V supply
or bipolar ±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.

__________Applications Information
Operation with
Supply Voltages Other than 15V
Using supply voltages less than ±15V will reduce the
analog signal range. The MAX308/MAX309 switches
operate with ±5V to ±20V bipolar supplies or with a
+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.
