MAX3094ECSE+

Overview

The MAX3094ECSE+ is a low-power, quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3V to +3.6V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via the Human Body Model and IEC 1000-4-2 standards. Propagation delays are guaranteed within ±10ns tolerance for device-to-device matching. It includes a 1nA shutdown mode and a fail-safe feature ensuring a logic-high output when inputs are open circuit. The input impedance allows up to 128 receivers on a bus. It is housed in a 16-pin Narrow SOIC package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated ±15kV electrostatic discharge protection on all receiver inputs
• Guaranteed propagation-delay matching between devices across production lots
• Quarter-unit-load input impedance enabling high node density on communication buses
• Fail-safe design guarantees a logic-high output state during open-circuit conditions

Applications

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

Procurement Notes

Verify the specific suffix 'CSE+' against official documentation to confirm the commercial temperature range (0°C to +70°C) and narrow SOIC packaging. Ensure compatibility with existing board layouts as this component serves as a pin-compatible upgrade to legacy parts. Confirm supply chain availability through authorized distributors given potential restricted status.

Selection Notes

Select the MAX3094ECSE+ when a low-power, quad receiver is required for 3.3V systems. It is suitable for designs needing robust ESD protection without external components. Consider the ±10ns delay tolerance for applications requiring precise timing alignment between multiple receiver channels. Verify that the 10Mbps maximum data rate meets system requirements.

Part Context

This component 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 operation. Both share similar features but differ in supply voltage and propagation delay specifications. They serve as direct replacements for industry-standard parts like the ’34C86.

Replacement Considerations

The MAX3094ECSE+ is documented as a pin-compatible, low-power upgrade to the industry-standard ’34C86. Designers replacing legacy ’34C86 components should verify power supply voltage differences and ensure the new propagation delay characteristics fit the system timing constraints.
