Conclusion The MAX3283E successfully meets the quality and reliability standards required of all Maxim products. In addition, Maxim's continuous reliability monitoring program ensures that all outgoing product will continue to meet Maxim's quality and reliability standards.

I. Device Description A. General The MAX3283E is a single receiver designed for RS-485 and RS-422 communication. This devices guarantee data rates up to 52Mbps, even with a 3V power supply. Excellent propagation delay (15ns max) and package-to-package skew time (8ns max) make this device ideal for multidrop clock distribution applications. The MAX3283E has true fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are opened or shorted. The receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). This device features 1/4-unit-load receiver input impedance, allowing up to 128 receivers on the same bus. The MAX3283E single receivers have a receiver enable (EN or EN-bar) function and are offered in a 6-pin SOT23 package.

V. Quality Assurance Information A. Quality Assurance Contacts: Jim Pedicord (Reliability Lab Manager) Bryan Preeshl ( Executive Director of QA) Kenneth Huening (Vice President) B. Outgoing Inspection Level: 0.1% for all electrical parameters guaranteed by the Datasheet. 0.1% For all Visual Defects.
C. Observed Outgoing Defect Rate: < 50 ppm D. Sampling Plan: Mil-Std-105D VI. Reliability Evaluation A. Accelerated Life Test The results of the 135C biased (static) life test are shown in Table 1. Using these results, the Failure Rate () is calculated as follows: = 1 = MTTF 1.83 (Chi square value for MTTF upper limit) 192 x 4389 x 240 x 2 Temperature Acceleration factor assuming an activation energy of 0.8eV = 4.52 x 10-9 = 4.52 F.I.T. (60% confidence level @ 25C)
This low failure rate represents data collected from Maxim's reliability qualification and monitor programs. Maxim also performs w eekly 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 Burn-In Schematic (Spec.# 06-5867) 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 (RR-1M) located on the Maxim website at http://www.maxim-ic.com . 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 85C/85%RH or HAST tests are performed quarterly per device/package family. C. E.S.D. and Latch-Up Testing The RT33-3 die type has been found to have all pins able to withstand a transient pulse of 1000V, per MilStd-883 Method 3015 (reference attached ESD Test Circuit). Additionally, the MAX3283E has achieved 15kV ESD protection using both methods 3015 and IEC 801-2 (air-gap discharge) on the I/O pins. Latch-Up testing has shown that this device withstands a current of 250mA and/or 20V.
