MAX3093ECUE+

Overview

The MAX3093ECUE+ is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via Human Body Model, ±8kV IEC 1000-4-2 Contact Discharge, and ±15kV Air-Gap Discharge. Propagation delays are guaranteed within ±8ns tolerance for device-to-device matching. It includes a low-power shutdown mode with 1nA typical supply current and a fail-safe feature ensuring logic-high output on open inputs. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides robust electrostatic discharge protection suitable for harsh environments
• Ensures precise timing synchronization through tightly matched propagation delays
• Supports high bus density by allowing up to 128 receivers on the network
• Minimizes power consumption with a dedicated low-power shutdown state

Applications

• Telecommunications equipment
• Rugged RS-422/RS-485/RS-423 bus receiver systems
• Receivers for ESD-sensitive applications
• Level translators

Procurement Notes

Verify that the specific part number suffix matches the required temperature grade and packaging format. Confirm the voltage supply requirements align with the system design, as this model is specified for +5V operation. Ensure compatibility with existing PCB footprints for the 16-pin TSSOP package before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring quad differential line reception at speeds up to 10Mbps. It serves as a pin-compatible, low-power upgrade to the industry-standard '34C86. Consider its quarter-unit-load input impedance if the application requires connecting a large number of devices to a single bus segment.

Part Context

This device belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. While the MAX3094E variant operates from a +3.3V supply, the MAX3093E is specifically designed for +5V applications. Both share identical pinouts and functional characteristics, differing primarily in their supply voltage specifications.

Replacement Considerations

The MAX3093E is documented as a pin-compatible, low-power upgrade to the industry-standard '34C86.
