MAX3093ECSE+T

Overview

The MAX3093ECSE+T is a low-power, 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 on all inputs. Propagation delays are guaranteed within ±8ns tolerance for precise matching across production lots. It includes a 1nA shutdown mode and fail-safe logic that ensures a high output when inputs are open. The component is housed in a 16-pin Narrow SO package.

Feature Summary

• Provides robust electrostatic discharge protection rated at ±15kV via Human Body Model and IEC 1000-4-2 standards.
• Features a low-power shutdown mode that reduces supply current to approximately 1nA with outputs in a high-impedance state.
• Ensures reliable communication through fail-safe circuitry that guarantees a logic-high output during open-circuit input conditions.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the procurement channel provides valid traceability for the component batch.

Selection Notes

Select this component for systems requiring a dedicated quad receiver compatible with standard RS-422/RS-485 protocols. It serves as a pin-compatible upgrade to the industry-standard '34C86. Verify that the system power supply aligns with the required +5V operating voltage for optimal performance.

Part Context

This part belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. The MAX3093E variant specifically targets +5V operation, whereas the MAX3094E is designed for +3.3V supplies. Both share identical pinouts and functional characteristics regarding ESD protection and data rates.

Replacement Considerations

The MAX3093ECSE+T is explicitly documented as a pin-compatible, low-power upgrade to the industry-standard '34C86 receiver. Designers replacing legacy components should verify that the existing board layout accommodates the Narrow SO-16 package dimensions.
