GENERAL DESCRIPTION
The ADG406, ADG407 and ADG426 are monolithic CMOS
analog multiplexers. The ADG406 and ADG426 switch one of
sixteen inputs to a common output as determined by the 4-bit
binary address lines A0, A1, A2 and A3. The ADG426 has onchip address and control latches that facilitate microprocessor
interfacing. The ADG407 switches one of eight differential
inputs to a common differential output as determined by the 3bit binary address lines A0, A1 and A2. An EN input on all
devices is used to enable or disable the device. When disabled,
all channels are switched OFF.
The ADG406/ADG407/ADG426 are designed on an enhanced
2
LC
MOS process that provides low power dissipation yet gives
high switching speed and low on resistance. These features
make the parts suitable for high speed data acquisition systems
and audio signal switching. Low power dissipation makes the
parts suitable for battery powered systems. Each channel
conducts equally well in both directions when ON and has an
input signal range which extends to the supplies. In the OFF
condition, signal levels up to the supplies are blocked. All
channels exhibit break before make switching action preventing
momentary shorting when switching channels. Inherent in the
design is low charge injection for minimum transients when
switching the digital inputs.

PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG406/ADG407/ADG426 are fabricated on an
enhanced LC
2
MOS process giving an increased signal range
which extends to the supply rails
2. Low Power Dissipation
3. Low R
ON
4. Single/Dual Supply Operation
5. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG406/ADG407/ADG426 can be operated from a single
rail power supply. The parts are fully specified with a single
+12 V power supply and will remain functional with single
supplies as low as +5 V.

NOTES
1
Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability. Only
one absolute maximum rating may be applied at any one time.
2
Overvoltages at A, S, D, WR or RS will be clamped by internal diodes. Current
should be limited to the maximum ratings given.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although these devices feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
Figure 1 shows the timing sequence for latching the switch
address and enable inputs. The latches are level sensitive;
therefore, while
WR is held low, the latches are transparent and
the switches respond to the address and enable inputs. This
input data is latched on the rising edge of
