MAX3095EPE+

Overview

The MAX3095EPE+ 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 Human Body Model, ±15kV IEC 1000-4-2 Air-Gap Discharge, and ±8kV Contact Discharge. Input hysteresis is 45mV with a differential threshold of ±200mV. Operating temperature range is -40°C to +85°C in a 16-pin Plastic DIP package. Supply current is typically 2.4mA, dropping to 1nA in shutdown mode.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay matching within ±8ns across production lots
• Quarter-unit-load input impedance supporting up to 128 receivers per bus
• Fail-safe feature ensuring logic-high output 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 'EPE+' corresponds to the extended temperature range (-40°C to +85°C) and lead-free PDIP-16 packaging. Confirm that the ordering code matches the manufacturer's official documentation to ensure correct voltage operation at +5V. Cross-reference the datasheet revision date to validate electrical characteristics against the purchased component lot.

Selection Notes

Select this component when upgrading legacy '26LS32 designs requiring lower power consumption and enhanced ESD robustness. Ensure the system utilizes a +5V supply rail, as the MAX3095 is not compatible with +3.3V logic levels unlike the MAX3096 variant. Verify that the 10Mbps maximum data rate aligns with the communication protocol requirements of the target application.

Part Context

The MAX3095 serves as a low-power, pin-compatible replacement for the industry-standard SN75176 or similar quad receivers. It belongs to a family alongside the MAX3096, which differs primarily in operating voltage (+3.3V). The EPE+ designation specifically identifies the industrial temperature grade and plastic dual in-line package configuration within the broader MAX3095 product line.

Replacement Considerations

The MAX3096 is a direct pin-compatible alternative if the system operates on a +3.3V supply instead of +5V. Other quad RS-422/RS-485 receivers may require external ESD protection components to match the integrated ±15kV capabilities of the MAX3095.
