MAX481MJA

Overview

The MAX481MJA is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver within an 8-pin CERDIP package. The device supports data transmission rates up to 2.5Mbps with a typical quiescent supply current of 300µA. It operates from a single 5V power supply (4.75V to 5.25V) and features a low-power shutdown mode consuming only 0.1µA. The component is rated for military-grade operation across a temperature range of -55°C to +125°C.

Feature Summary

Half-duplex communication capability for multipoint bus networks
Low-power shutdown mode reducing supply current to 0.1µA
Driver outputs protected against short circuits and thermal overload
Receiver input includes fail-safe feature ensuring logic-high output during open-circuit conditions

Applications

Industrial-control local area networks
Low-power RS-485 transceivers
Low-power RS-422 transceivers
Level translators

Procurement Notes

Verify the specific ordering suffix MJA confirms the military temperature range (-55°C to +125°C) and ceramic dual in-line package (CERDIP). Confirm RoHS compliance status as military parts may differ from commercial variants. Ensure the source document explicitly lists this part number to validate authenticity before procurement.

Selection Notes

Select the MAX481MJA when designing systems requiring high-speed data rates up to 2.5Mbps in harsh environments. This variant is appropriate for applications demanding extended temperature stability and rugged packaging. Verify that half-duplex operation aligns with system requirements, as full-duplex alternatives like the MAX490 exist within the same family.

Part Context

The MAX481MJA belongs to the MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487 series of low-power transceivers. These devices are designed for bidirectional data communications on multipoint bus transmission lines. The 'MJA' suffix specifically denotes the military-grade temperature range and ceramic package construction.
