MAX490MJA Technical Overview: Verified Parameters Before Sourcing
MAXIM MAX490MJA is a interface and logic device cataloged in Interface, Logic & Bus for Aerospace & Defense programs. Unlike a family-level listing, the complete ordering code matters: package, temperature grade, speed option, screening level and shipment format can change with a suffix. The structured reference data for this exact part identifies Supply Voltage-Nom 5, Supply Voltage-Min 4.75, Supply Voltage-Max 5.25, Min Operating Temperature -55.
These values are useful for initial BOM and sourcing review, but engineering approval should still use the latest manufacturer-controlled datasheet, package drawing and change notices. For availability, lot/date code and documentation, send Sparkle Electronics the complete MAX490MJA requirement.

What the Specifications Mean in a Design Review
For this interface and logic device, the main compatibility checks are logic function, channel count, propagation delay, voltage thresholds, drive current and bus compatibility. A replacement should not be approved from the family name alone. The values below need to be checked against the schematic, PCB footprint, power tree, timing constraints, thermal analysis and program qualification baseline:
- Supply Voltage-Nom: 5
- Supply Voltage-Min: 4.75
- Supply Voltage-Max: 5.25
- Min Operating Temperature: -55
- Max Operating Temperature: 125
- Temperature Grade: MILITARY
- Pin Count: 8
Minimum and maximum values are not interchangeable with typical test values, and package-level compatibility does not guarantee pin, timing or firmware compatibility. Where the assembly is used in high-reliability equipment, confirm the required screening, traceability, lead finish and environmental documentation before purchase.
MAX490MJA and Related MAXIM Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- MAXIM MAX485MJA — compare the exact architecture, package, speed or grade before substitution.
- MAXIM DG506ACK — compare the exact architecture, package, speed or grade before substitution.
- MAXIM MAX691AMJE — compare the exact architecture, package, speed or grade before substitution.
- MAXIM MAX232AMJE — compare the exact architecture, package, speed or grade before substitution.
When comparing these devices, start with the exact function and architecture, then verify package and pinout, voltage rails, speed or bandwidth, operating temperature and qualification grade. If any of those differ, an engineering redesign or requalification may be required.
Package, Temperature and Ordering-Code Checks
The orderable code MAX490MJA must be kept intact on the RFQ. Confirm the manufacturer marking, package drawing, terminal finish, moisture handling, operating-temperature requirement and packing format. For obsolete or long-stored material, define acceptable date codes and inspection criteria before quotation rather than after delivery.
Sourcing teams should also request the documentation appropriate to the program: Certificate of Conformance, packing and label photographs, lot/date-code information, traceability, visual inspection, X-ray or electrical testing when required. See our quality-control approach and the broader Interface, Logic & Bus selection.
Applications and Procurement Context
MAX490MJA may be evaluated for Aerospace & Defense systems where its verified electrical limits, package and temperature range match the approved design. Typical work includes new production, repair, lifecycle extension and last-time-buy planning. Application labels describe catalog relevance; final suitability remains a system-level engineering decision.
Frequently Asked Questions
What are the main MAX490MJA parameters?
