GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG438F/ADG439F are CMOS analog multiplexers, the
ADG438F comprising 8 single channels and the ADG439F
comprising four differential channels. These multiplexers provide fault protection. Using a series n-channel, p-channel, nchannel MOSFET structure, both device and signal source
protection is provided in the event of an overvoltage or power
loss. The multiplexer can withstand continuous overvoltage
inputs from –40 V to +55 V. During fault conditions, the multiplexer input (or output) appears as an open circuit and only a
few nanoamperes of leakage current will flow. This protects not
only the multiplexer and the circuitry driven by the multiplexer,
but also protects the sensors or signal sources which drive the
multiplexer.
1. Fault Protection.
The ADG438F/ADG439F can withstand continuous voltage inputs up to –40 V or +55 V. When a fault occurs due
to the power supplies being turned off, all the channels
are turned off and only a leakage current of a few nanoamperes flows.
The ADG438F switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and
A2. The ADG439F switches one of four differential inputs to a
common differential output as determined by the 2-bit binary
address lines A0 and A1. An EN input on each device is used to
enable or disable the device. When disabled, all channels are
switched OFF.
6. Trench Isolation Eliminates Latch-up.
A dielectric trench separates the p- and n-channel MOSFETs
thereby preventing latch-up.
2. ON channel turns OFF while fault exists.
3. Low RON.
4. Fast Switching Times.
5. Break-Before-Make Switching.
Switches are guaranteed break-before-make so that input
signals are protected against momentary shorting.
7. Improved OFF Isolation.
Trench isolation enhances the channel-to-channel isolation
of the ADG438F/ADG439F.

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 the ADG438F/ADG439F features proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic dischar ges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

ADG438F/ADG439F
n-channel threshold voltage (VTN). When a voltage more negative than VSS is applied to the multiplexer, the p-channel
MOSFET will turn off since the analog input is more negative
than the difference between VSS and the p-channel threshold
voltage (VTP).
THEORY OF OPERATION
The ADG438F/ADG439F multiplexers are capable of withstanding overvoltages from –40 V to +55 V, irrespective of
whether the power supplies are present or not. Each channel of
the multiplexer consists of an n-channel MOSFET, a p-channel
MOSFET and an n-channel MOSFET, connected in series.
When the analog input exceeds the power supplies, one of the
MOSFETs will switch off, limiting the current to sub-microamp
levels, thereby preventing the overvoltage from damaging any
circuitry following the multiplexer. Figure 12 illustrates the
channel architecture that enables these multiplexers to withstand continuous overvoltages.
When the power supplies are present but the channel is off,
again either the p-channel MOSFET or one of the n-channel
MOSFETs will remain off when an overvoltage occurs.
Finally, when the power supplies are off, the gate of each
MOSFET will be at ground. A negative overvoltage switches on
the first n-channel MOSFET but the bias produced by the
overvoltage causes the p-channel MOSFET to remain turned
off. With a positive overvoltage, the first MOSFET in the series
will remain off since the gate to source voltage applied to this
MOSFET is negative.
When an analog input of VSS + 1.2 V to VDD – 0.8 V is applied
to the ADG438F/ADG439F, the multiplexer behaves as a
standard multiplexer, with specifications similar to a standard
multiplexer, for example, the on-resistance is 180 Ω typically.
However, when an overvoltage is applied to the device, one of
the three MOSFETs will turn off.
Figures 10 to 13 show the conditions of the three MOSFETs for
the various overvoltage situations. When the analog input applied to an ON channel approaches the positive power supply
line, the n-channel MOSFET turns OFF since the voltage on
the analog input exceeds the difference between VDD and the
Q1
+55V
OVERVOLTAGE
Q2
During fault conditions, the leakage current into and out of the
ADG438F/ADG439F is limited to a few microamps. This protects the multiplexer and succeeding circuitry from over stresses
as well as protecting the signal sources which drive the multiplexer. Also, the other channels of the multiplexer will be
undisturbed by the overvoltage and will continue to operate
normally.
