DG408/409
Vishay Siliconix
8-Ch/Dual 4-Ch High-Performance CMOS Analog Multiplexers
DESCRIPTION
FEATURES
The DG408 is an 8-channel single-ended analog multiplexer
designed to connect one of eight inputs to a common output
as determined by a 3-bit binary address (A0, A1, A2). The
DG409 is a dual 4-channel differential analog multiplexer
designed to connect one of four differential inputs to a
common dual output as determined by its 2-bit binary
address (A0, A1). Break-before-make switching action
protects against momentary crosstalk between adjacent
channels.
An on channel conducts current equally well in both
directions. In the off state each channel blocks voltages up
to the power supply rails. An enable (EN) function allows the
user to reset the multiplexer/demultiplexer to all switches off
for stacking several devices. All control inputs, address (Ax)
and enable (EN) are TTL compatible over the full specified
operating temperature range.

Applications for the DG408/409 include high speed data
acquisition, audio signal switching and routing, ATE
systems, and avionics. High performance and low power
dissipation make them ideal for battery operated and remote
instrumentation applications.
Designed in the 44 V silicon-gate CMOS process, the
absolute maximum voltage rating is extended to 44 V.
Additionally, single supply operation is also allowed. An
epitaxial layer prevents latchup.
For additional information please see Technical Article
TA201 (FaxBack Number 70600).

Notes:
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
g. ΔrDS(on) = rDS(on) MAX - rDS(on) MIN.
h. Worst case isolation occurs on Channel 4 due to proximity to the drain pin.
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.

APPLICATIONS HINTS
Overvoltage Protection
A very convenient form of overvoltage protection consists of
adding two small signal diodes (1N4148, 1N914 type) in
series with the supply pins (see Figure 10). This
arrangement effectively blocks the flow of reverse currents.
It also floats the supply pin above or below the normal V+ or
V- value. In this case the overvoltage signal actually
becomes the power supply of the IC. From the point of view
of the chip, nothing has changed, as long as the difference
VS - (V-) doesn’t exceed + 44 V. The addition of these diodes
will reduce the analog signal range to 1 V below V+ and 1 V
above V-, but it preserves the low channel resistance and low
leakage characteristics.
