DESCRIPTION
The DG9408/9409 uses BiCMOS wafer fabrication
technology that allows the DG9408/9409 to operate on single
and dual supplies. Single supply voltage ranges from 3- to
12-V while dual supply operation is recommended with "3 to
"6 V.
as determined by a 3-bit binary address (A0, A1, A2). The
DG9409 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.
The DG9408 is an 8-channel single-ended analog multiplexer
designed to connect one of eight inputs to a common output

Notes
a. Signals on SX, DX or INX exceeding V+ or V- will be clamped by internal
diodes. Limit forward diode current to maximum current ratings.
b. All leads soldered or welded to PC board.
c. Derate 23.5 mW/_C above 70_C.
d. Manual soldering with soldering iron is not recommended for leadless
components. The QFN is a leadless package. The end of the lead
terminal is exposed copper (not plated) as a result of the singulation
process in manufacturing. A solder fillet at the exposed copper lip cannot
be guaranteed and is not required to ensure adequate bottom side solder
interconnection.

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 do 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.
