MAX3283EAUT/GG8

Overview

The MAX3283EAUT/GG8 is a single receiver designed for RS-485 and RS-422 communication, operating within a 3V to 5.5V power-supply range. It guarantees data rates up to 52Mbps with a maximum propagation delay of 15ns and package-to-package skew time of 8ns. The device features true fail-safe circuitry that ensures a logic-high output when inputs are open or shorted. It includes an active-low enable pin (EN) for redundant operation and three-state outputs. Packaged in a 6-pin SOT23, it supports up to 128 receivers on the bus due to its 1/4-unit-load input impedance.

Feature Summary

• True fail-safe architecture guarantees a high receiver output when inputs are open or shorted
• Active-low enable pin allows for redundant receiver configurations and three-state control
• Low package-to-package skew time enables precise multidrop clock distribution applications
• High ESD protection ratings ensure robustness against static discharge events

Applications

• Multidrop clock distribution networks
• Telecom racks and base stations
• Industrial control systems
• Local area networks

Procurement Notes

Verify the specific suffix GG8 against official documentation to confirm exact packaging and RoHS compliance status. Confirm availability through authorized distributors as discontinuation notices may apply to certain variants. Ensure the active-low enable requirement matches the system design before procurement.

Selection Notes

Select this component when a single receiver with an active-low enable signal is required for RS-485 or RS-422 buses. It is suitable for designs needing tight propagation delay matching across multiple devices. Consider the 6-pin SOT23 footprint constraints and verify that the 3V to 5.5V supply range aligns with the target application voltage.

Part Context

This part belongs to the MAX3280E/MAX3281E/MAX3283E/MAX3284E family of low-voltage, fail-safe receivers manufactured by Analog Devices / Maxim Integrated. While sharing core electrical characteristics like the 52Mbps rate and fail-safe behavior, the MAX3283E is distinguished by its active-low enable pin, unlike the MAX3281E which uses an active-high enable.

Replacement Considerations

MAX3281EAUT+T serves as a functional alternative if the system requires an active-high enable pin instead of active-low. Both share identical electrical specifications and package dimensions.
