MAX1487EESA+TG104

Drivers, Receivers, Transceivers Overview

The MAX1487EESA+TG104 is a low-power, half-duplex RS-485 and RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver within an 8-pin SOIC package. The device supports data transmission rates up to 2.5Mbps with an unrestricted slew rate. It operates on a single +5V supply (4.75V to 5.25V) and features ±15kV ESD protection on all pins without latchup. The receiver input impedance is 48kΩ (1/4-unit load), allowing up to 128 transceivers on the bus. Key electrical parameters include a typical no-load supply current of 300µA and a maximum power dissipation of 471mW in the SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV electrostatic discharge (ESD) protection on driver outputs and receiver inputs without latchup.
• Features quarter-unit-load receiver input impedance to support high node counts on multipoint buses.
• Includes thermal shutdown circuitry to protect against excessive power dissipation and short-circuit current limiting.

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485 Transceivers
• Low-Power RS-422 Transceivers
• Industrial-Control Local Area Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TG104 against official manufacturer documentation to confirm packaging or material specifications. Confirm component availability status as distribution channels may list obsolete or discontinued inventory. Ensure the ordering information matches the required temperature range and package variant for the intended design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data rates up to 2.5Mbps where standard slew-rate limitations are unsuitable. The 1/4-unit load receiver characteristic makes it appropriate for networks requiring more than 32 nodes. Verify that the system environment does not require the lower data rate and reduced EMI characteristics provided by slew-rate-limited variants like the MAX487E.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E family of low-power transceivers designed for harsh environments. Unlike slew-rate-limited members of the series, the MAX1487E allows for faster data transmission speeds while maintaining low power consumption and robust ESD protection capabilities.
