MAX3093EEPE+

Overview

The MAX3093EEPE+ 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 IEC 1000-4-2 Air-Gap Discharge, ±8kV Contact Discharge, and ±15kV Human Body Model standards. Propagation delays are guaranteed within ±8ns tolerance for precise matching across production lots. It includes a 1nA low-power shutdown mode and a fail-safe feature ensuring a logic-high output during open-circuit conditions. The input impedance allows up to 128 receivers on a bus. It is housed in a 16-pin Plastic DIP package and functions over an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection meeting IEC 1000-4-2 standards for harsh environments.
• Ensures precise timing synchronization through tightly matched propagation-delay tolerances between devices.
• Enables extensive network scalability with quarter-unit-load input impedance supporting up to 128 receivers per bus.

Applications

• Telecommunications Equipment
• Rugged RS-422/RS-485/RS-423 Bus Receiver Systems
• Receivers for ESD-Sensitive Applications

Procurement Notes

Verify the specific ordering suffix EEPE+ corresponds to the -40°C to +85°C industrial temperature range and the 16-pin Plastic DIP package configuration. Confirm that the component is sourced directly from authorized distributors or the manufacturer to ensure authenticity. Check for RoHS compliance status as indicated in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when a +5V supply voltage is required for RS-422 or RS-485 receiver applications. Choose this part if strict propagation delay matching is critical for multi-channel data transmission systems. Consider this device for designs requiring high ESD immunity without external protection components and low quiescent current consumption in standby modes.

Part Context

This component belongs to the MAX3093E/MAX3094E family of low-power, rugged quad receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '34C86 receiver. While the MAX3093E operates at +5V, the MAX3094E variant operates at +3.3V. Both share identical functional characteristics regarding ESD protection, data rates, and package options.

Replacement Considerations

The MAX3093E/MAX3094E are explicitly documented as pin-compatible upgrades to the '34C86 receiver. Designers replacing legacy '34C86 components can utilize this part without modifying the PCB footprint, provided the system voltage aligns with the +5V requirement of the MAX3093E series.
