MAX1480BCPI Equivalent & Substitute Parts

Part Overview

The MAX1480BCPI is a half-duplex RS422/RS485 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin DIP package. This component functions as a single driver/receiver interface for serial communication protocols requiring robust noise immunity and extended cable distances. The MAX1480BCPI is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX1480BCPI are determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS422/RS485 half-duplex operation
• Electrical Specifications: 1/1 driver/receiver configuration, 250 kbps data rate, 70 mV receiver hysteresis, 4.5V–5.5V supply voltage range
• Thermal Range: 0°C to 70°C operating temperature
• Package Specification: 28-pin DIP form factor with identical pinout and mechanical dimensions
• Moisture Sensitivity: MSL 1 rating
• Regulatory Compliance: REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001

All substitute parts listed maintain 100% parametric equivalence with the main part across these criteria. Differences in product status (active vs. obsolete) and RoHS compliance reflect manufacturing and regulatory updates without affecting functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to the MAX1480BCPI and are suitable for direct replacement in applications requiring RS422/RS485 half-duplex transceiver functionality. Selection among active alternatives should be based on the following factors:

Product Status: The MAX1480BCPI is obsolete. All substitute parts (MAX1480BCPI+, MAX1480BEPI+, MAX1480CCPI+, MAX1480CEPI+) maintain active product status, ensuring long-term availability and manufacturing support.

Regulatory Compliance: All substitute parts are ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The original MAX1480BCPI is RoHS non-compliant and should be replaced in new designs subject to RoHS requirements.

Inventory Availability: MAX1480BEPI+ offers the highest inventory level (6017 units), followed by MAX1480BCPI+ and MAX1480CCPI+ (2200 units each), and MAX1480CEPI+ (1376 units). Selection may be influenced by supply chain requirements and lead time considerations.

Packaging and Handling: All substitute parts are supplied in tube packaging with MSL 1 rating, indicating unlimited shelf life under standard storage conditions. No special moisture control measures are required.

Frequently Asked Questions (FAQ)

Q: Can MAX1480BCPI+ be used as a direct replacement for MAX1480BCPI?

A: Yes. MAX1480BCPI+ is parametrically equivalent across all electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and RoHS3 compliance. Pin configuration, package dimensions, and functional performance are identical.

Q: What is the difference between MAX1480BCPI, MAX1480BEPI+, and MAX1480CCPI+?

A: All three parts are functionally identical in terms of electrical performance and package specification. Differences exist only in product status (obsolete vs. active) and RoHS compliance. The alphanumeric suffix indicates manufacturing date code and compliance revision; however, all variants maintain the same 28-DIP pinout and RS422/RS485 transceiver functionality.

Q: Are these parts suitable for new product designs?

A: Yes. Active substitute parts (MAX1480BCPI+, MAX1480BEPI+, MAX1480CCPI+, MAX1480CEPI+) are appropriate for new designs. The original MAX1480BCPI should not be used in new designs due to obsolete status. For designs requiring RoHS compliance, all active substitutes meet ROHS3 requirements.

Q: What is the operating temperature range for these transceivers?

A: All parts operate within the 0°C to 70°C temperature range. This specification applies uniformly across the main part and all substitutes. Applications requiring extended temperature ranges require alternative part selection outside this family.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts share identical 28-DIP package dimensions (0.600", 15.24mm) and pinout. No PCB layout modifications are required for substitution. Through-hole mounting remains consistent across all variants.

Q: What is the maximum data rate supported by these transceivers?

A: The maximum data rate is 250 kbps for all parts in this family. This specification is fixed and applies uniformly to the main part and all substitutes.

Q: Are there any supply voltage differences between the variants?

A: No. All parts require a 4.5V to 5.5V supply voltage range. Power supply design and decoupling requirements remain identical across all variants.
