I. Device Description
A. General
Maxim's redesigned DG409 CMOS analog multiplexer now feature guaranteed matching between channels (8
max) and flatness over the specified signal range (9 max). This low on-resistance mux (100 max) conducts
equally well in either direction and features guaranteed low charge injection (15pC max). In addition, it offers low
input off-leakage current over temperature—less than 5nA at +85°C.
The DG409 is a dual 4-channel multiplexer/demultiplexer, operating with a +5V to +30V single supply and with ±5V
to ±20V dual supplies. ESD protection is guaranteed to be greater than 2000V per Method 3015.7 of MIL-STD-883.
This improved mux is pin-compatible plug-in upgrade for the industry standard DG408.

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 135°C biased (static) life test are shown in Table 1. Using these results, the Failure
Rate (λ) is calculated as follows:
λ=
1
=
MTTF
1.83
(Chi square value for MTTF upper limit)
192 x 4389 x 480 x 2
Temperature Acceleration factor assuming an activation energy of 0.8eV
λ = 2.26 x 10-9
λ = 2.26 F.I.T. (60% confidence level @ 25°C)
This low failure rate represents data collected from Maxim’s reliability qualification and monitor programs.
Maxim also performs weekly Burn-In on samples from production to assure reliability of its processes. The
reliability required for lots which receive a burn-in qualification is 59 F.I.T. at a 60% confidence level, which equates
to 3 failures in an 80 piece sample. Maxim performs failure analysis on rejects from lots exceeding this level. The
attached Burn-In Schematic (Spec. # 06-5584) shows the static circuit used for this test. Maxim also performs
1000 hour life test monitors quarterly for each process. This data is published in the Product Reliability Report (RR1M).
B. Moisture Resistance Tests
Maxim evaluates pressure pot stress from every assembly process during qualification of each new design.
Pressure Pot testing must pass a 20% LTPD for acceptance. Additionally, industry standard 85°C/85%RH or
HAST tests are performed quarterly per device/package family.
C. E.S.D. and Latch-Up Testing
The AG56-1 die type has been found to have all pins able to withstand a transient pulse of ±3000V, per MilStd-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device
withstands a current of ±250mA.
