MAX3094ECUE+T

Overview

The MAX3094ECUE+T is a low-power, quad RS-422/RS-485 receiver designed for harsh environments. It operates from a single +3.0V to +3.6V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via the Human Body Model and ±8kV IEC 1000-4-2 Contact Discharge. Propagation delays are guaranteed within ±10ns of a predetermined value, ensuring tight device-to-device matching. It includes a 1nA shutdown mode and a fail-safe feature that guarantees a logic-high output when inputs are open circuit. The input impedance allows up to 128 receivers on a bus.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for robust operation in harsh environments
• Guaranteed propagation-delay tolerance between devices for precise timing synchronization
• Fail-safe design ensures a logic-high output state during open-circuit input conditions
• Quarter-unit-load input impedance enables connection of up to 128 receivers on a single bus

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates an industrial temperature range of 0°C to +70°C and 'UE' denotes the 16-pin TSSOP package. Confirm the '+T' suffix corresponds to tape-and-reel packaging as specified in the manufacturer's ordering information. Ensure compatibility with the required 3.3V supply voltage before finalizing procurement.

Selection Notes

Select this component when a 3.3V supply is required instead of the 5V variant (MAX3093E). It serves as a pin-compatible upgrade to the industry-standard SN75176 or similar legacy receivers. Choose this model if strict propagation delay matching across multiple channels or devices is necessary for system synchronization.

Part Context

This part belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. While the MAX3093E operates at 5V, the MAX3094E is optimized for 3.3V systems. Both share identical pinouts and functional characteristics, differing primarily in supply voltage requirements and specific propagation delay tolerances.

Replacement Considerations

Public confirmed substitutes include the MAX3093E for 5V applications. Legacy replacements may include the SN75176, though power consumption and ESD ratings differ.
