ADM3077EARZ

Drivers, Receivers, Transceivers Overview

The ADM3077EARZ is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices. It operates on a single 3.3 V supply and supports data rates up to 16 Mbps. The device features ±15 kV ESD protection on the bus pins, true fail-safe receiver inputs, and outputs that go high-Z when disabled or powered off. It utilizes an 8-lead narrow SOIC package and functions within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver operation
• Integrated hot-swap input structure on DE and RE pins for safe line insertion
• True fail-safe receiver inputs ensuring a logic high output when inputs are open or shorted

Drivers, Receivers, Transceivers Applications

• Power and energy metering systems
• Industrial control networks
• Lighting systems
• Telecommunications equipment
• Security systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating environment remains within the specified industrial temperature limits. Cross-reference the datasheet revision history to validate current performance characteristics before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring simultaneous transmission and reception at speeds up to 16 Mbps. It is suitable for multipoint bus configurations supporting up to 256 nodes. Consider alternatives like the ADM3078EYRZ if half-duplex operation or low power shutdown modes are required instead of the continuous full-duplex functionality provided here.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ADM307xE series of 3.3 V low-power data transceivers. The series includes variants with different duplex modes, data rates, and slew rate limitations. The ADM3077E specifically provides full-duplex operation without slew rate limiting, distinguishing it from lower-speed or half-duplex counterparts in the same family.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3077EESA+ serves as a functional equivalent within the same product family. Verify pin configuration and specific electrical parameters against the target application requirements before substitution.

Drivers, Receivers, Transceivers FAQ

Does the ADM3077EARZ support low power shutdown mode?

No, the ADM3077E does not feature a low power shutdown mode. This characteristic is available in other members of the ADM307xE series, such as the ADM3076E and ADM3078E.

What is the maximum number of transceivers supported on the bus?

The device has a 1/8 unit load receiver input impedance, allowing up to 256 transceivers to be connected on a single bus.

How does the fail-safe feature function?

The true fail-safe receiver inputs guarantee a logic high output level when the receiver inputs are open, shorted, or connected to a terminated transmission line with all drivers disabled, eliminating the need for external bias resistors.
