SP3084EEN-L RS422/RS485 Transceiver Equivalent & Substitute Parts

Part Overview

The SP3084EEN-L is a 1/1 full-duplex RS422/RS485 transceiver IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates across a 4.5V to 5.5V supply range with a 500 kbps data rate and supports industrial temperature ranges from -40°C to 85°C.

Substitute Part Grouping Explanation

Substitution for the SP3084EEN-L is determined by strict alignment of the following critical parameters:

Core Compatibility Criteria:

Protocol: RS422/RS485 full-duplex operation
Configuration: 1/1 driver/receiver
Package: 8-SOIC form factor (0.154", 3.90mm width)
Data Rate: 500 kbps minimum
Mounting: Surface mount technology
MSL Rating: 1 (Unlimited)

Voltage Supply Range Considerations: The original part operates at 4.5V ~ 5.5V. Substitutes with narrower ranges (4.75V ~ 5.25V) remain compatible within standard 5V supply applications but may not support extended low-voltage operation below 4.75V.

Temperature Range Considerations: The original part supports -40°C ~ 85°C. Substitutes with narrower ranges (0°C ~ 70°C) are suitable for commercial and industrial applications within this reduced window but do not support full military-grade temperature extremes.

Receiver Hysteresis: The original part specifies 100 mV hysteresis. One substitute (ADM4855ARZ) provides 20 mV hysteresis, which offers improved noise immunity but represents a functional difference.

Engineering Selection Recommendations

Direct Parametric Equivalents (Highest Compatibility):

MAX13084EESA+ and MAX13084EESA+T provide complete parametric equivalence to the SP3084EEN-L, matching voltage supply range (4.5V ~ 5.5V), operating temperature (-40°C ~ 85°C), and receiver hysteresis (100 mV). Both parts are active products with ROHS3 compliance and REACH unaffected status. Selection between tube (MAX13084EESA+) and tape & reel (MAX13084EESA+T) packaging depends on assembly volume and handling requirements.

Extended Temperature Range Substitutes:

MAX3084EESA+ and MAX3084ESA+ maintain the full -40°C ~ 85°C operating temperature range with 100 mV hysteresis but operate within a narrower voltage supply window (4.75V ~ 5.25V). These parts are suitable for applications with standard 5V supplies and do not require extended low-voltage operation. Both are active products with ROHS3 compliance.

Commercial Temperature Range Substitutes:

MAX3084CSA+, MAX3084CSA+T, MAX3084ECSA+, and MAX3084ECSA+T operate within a reduced temperature range (0°C ~ 70°C) and narrower voltage supply (4.75V ~ 5.25V). These parts are appropriate for commercial and light industrial applications that do not require military-grade temperature extremes. All are active products with ROHS3 compliance. Packaging options include tube and tape & reel formats.

Alternative with Enhanced Noise Immunity:

ADM4855ARZ from Analog Devices Inc. provides a functional alternative with improved receiver hysteresis (20 mV versus 100 mV), offering superior noise immunity in electrically noisy environments. This part maintains the full -40°C ~ 85°C temperature range but operates within 4.75V ~ 5.25V supply limits. The part is active and ROHS3 compliant.

All substitute parts maintain identical 8-SOIC package geometry, 500 kbps data rate, and 1/1 full-duplex RS422/RS485 configuration, ensuring direct functional replacement within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can MAX3084CSA+ replace SP3084EEN-L in all applications?

A: MAX3084CSA+ is functionally compatible for RS422/RS485 communication but operates within a reduced temperature range (0°C ~ 70°C) and narrower voltage supply (4.75V ~ 5.25V). It is suitable for commercial and light industrial applications operating within these limits. Applications requiring -40°C operation or extended low-voltage support below 4.75V require alternatives such as MAX3084EESA+ or MAX13084EESA+.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (standard plastic tube) is suitable for lower-volume applications and manual assembly. Tape & reel packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Both packaging formats contain identical die and electrical specifications. Selection depends on assembly process requirements and volume.

Q: Is ADM4855ARZ a direct replacement for SP3084EEN-L?

A: ADM4855ARZ is electrically compatible for RS422/RS485 operation but differs in receiver hysteresis (20 mV versus 100 mV). The lower hysteresis provides improved noise immunity in electrically noisy environments but represents a functional change. Voltage supply range is narrower (4.75V ~ 5.25V). The part is suitable as a replacement where enhanced noise performance is beneficial and supply voltage remains within 4.75V ~ 5.25V.

Q: Which substitute offers the closest match to SP3084EEN-L specifications?

A: MAX13084EESA+ and MAX13084EESA+T provide complete parametric equivalence, matching voltage supply (4.5V ~ 5.5V), operating temperature (-40°C ~ 85°C), receiver hysteresis (100 mV), and all other electrical specifications. These parts are active products with current manufacturing support and are the preferred direct replacements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Can I use MAX3084ECSA+ in place of MAX3084EESA+?

A: Both parts share identical electrical specifications (100 mV hysteresis, 500 kbps data rate, 1/1 configuration) but differ in operating temperature range. MAX3084ECSA+ operates 0°C ~ 70°C, while MAX3084EESA+ operates -40°C ~ 85°C. Selection depends on the application's temperature requirements. For applications requiring full industrial temperature range, MAX3084EESA+ is required.
