Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers
DESCRIPTION
The DG3408, DG3409 uses BiCMOS wafer fabrication
technology that allows the DG3408/3409 to operate on sin-
gle and dual supplies. Single supply voltage ranges from 3
to 12 V while dual supply operation is recommended with
± 3 to ± 6 V.
The DG3408 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 DG3409 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 to protect against momentary crosstalk
between adjacent channels.
FEATURES

Notes:
a. Leakage parameters are guaranteed by worst case test condition and not subject to production test.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
d. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
g. RDON = RDON Max - RDON Min.
h. Worst case isolation occurs on Channel 4 due to proximity to the drain pin.
i. RDON flatness is measured as the difference between the minimum and maximum measured values across a defined Analog signal.
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.
