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 on all inputs, ensuring reliability in harsh environments. It includes a low-power shutdown mode with typical current consumption of 1nA. The receivers have a quarter-unit-load input impedance, allowing up to 128 devices on a bus. Propagation delays are guaranteed within ±8ns tolerance for precise timing matching. The component is housed in a 16-pin Plastic DIP package and functions across an extended temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection meeting IEC 1000-4-2 standards for air-gap and contact discharge scenarios.
• Features a low-power shutdown mode that reduces supply current to approximately 1nA when enabled.
• Ensures high-speed signal integrity through tightly matched propagation delay tolerances between individual units.

Applications

• Telecommunications equipment requiring reliable serial communication interfaces
• Rugged RS-422/RS-485/RS-423 bus receiver networks
• Level translators for ESD-sensitive digital applications

Procurement Notes

Verify the specific ordering suffix EEPE corresponds to the required 16-pin Plastic DIP package and the -40°C to +85°C industrial temperature grade. Confirm that the +5V supply voltage requirement aligns with the target system design, as this variant differs from the 3.3V MAX3094E series. Ensure compatibility with existing PCB footprints designed for standard DIP-16 configurations.

Selection Notes

Select the MAX3093EEPE when a +5V logic interface is required alongside high ESD immunity for industrial or telecommunications environments. This part serves as a pin-compatible upgrade to legacy '34C86 receivers while offering superior power efficiency and tighter propagation delay matching. Consider the 128-receiver bus capacity if designing large-scale multi-drop networks.

Part Context

This component belongs to the MAX3093E/MAX3094E family of low-power quad receivers. The MAX3093E specifically denotes the +5V operation variant, whereas the MAX3094E operates at +3.3V. Both share identical pinouts and functional characteristics, differing primarily in supply voltage requirements and propagation delay specifications.

Replacement Considerations

The datasheet identifies the MAX3093E/MAX3094E as pin-compatible upgrades to the industry-standard '34C86 receiver. Designers replacing legacy parts should verify that the new device's lower input impedance (quarter-unit-load) does not exceed the driver's capability on the bus.
