MAX3093EEUE+T

Overview

The MAX3093EEUE+T is a low-power, quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via IEC 1000-4-2 Air-Gap Discharge and Human Body Model standards. Supply current is typically 2.4mA with a shutdown mode drawing less than 1nA. Propagation delay ranges from 65ns to 98ns at TA = -40°C to +85°C. Input resistance is 48kΩ, allowing up to 128 receivers on the bus. It is housed in a 16-pin TSSOP package.

Feature Summary

• Provides robust electrostatic discharge protection for harsh environments
• Features guaranteed propagation-delay matching between devices
• Includes fail-safe logic-high output when inputs are open circuit
• Offers ultra-low power consumption with a dedicated shutdown mode

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 ordering suffix 'E' confirms the extended temperature range of -40°C to +85°C and 'U' specifies the TSSOP package. Confirm '+T' indicates tape-and-reel packaging. Ensure the component matches the specific voltage requirements of the +5V system design.

Selection Notes

Select this component for designs requiring high-speed differential signaling with strict timing synchronization. The tight propagation delay tolerance ensures minimal skew across multiple channels. Verify that the +5V supply rail aligns with the system architecture before implementation.

Part Context

This part belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. It serves as a pin-compatible upgrade to the industry-standard '34C86. While the MAX3094E operates at +3.3V, the MAX3093E is specifically designed for +5V operation.

Replacement Considerations

The MAX3093E/MAX3094E are direct pin-compatible upgrades to the '34C86. Designers replacing legacy components should verify that the new ESD protection levels meet the application's environmental requirements.

FAQ

How does the MAX3093E handle an open-circuit input?

The device includes a fail-safe feature that guarantees a logic-high output if the input is left open circuit.

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

Due to its quarter-unit-load input impedance, the MAX3093E allows up to 128 receivers on the same bus.

What is the typical current draw in shutdown mode?

In shutdown mode, where ENAC and ENBD are low, the device draws less than 1nA of supply current.
