MAX1480ACPI RS422/RS485 Half-Duplex Transceiver Equivalent & Substitute Parts

Part Overview

The MAX1480ACPI is a half-duplex RS422/RS485 transceiver interface IC manufactured by Analog Devices Inc./Maxim Integrated in a 28-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MAX1480ACPI provides single driver/receiver functionality with a 2.5 Mbps data rate, suitable for industrial communication applications requiring RS422 or RS485 protocol support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX1480ACPI are determined by strict equivalence across the following critical parameters:

• Protocol support: RS422 and RS485
• Driver/Receiver configuration: 1/1 (single driver, single receiver)
• Duplex mode: Half-duplex operation
• Data rate: 2.5 Mbps
• Receiver hysteresis: 70 mV
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Package type: 28-DIP (0.600", 15.24mm)
• Mounting type: Through Hole

All substitute parts listed maintain identical electrical and mechanical specifications. Differences exist only in product status (active vs. obsolete), packaging format (tube vs. standard), and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, selection among substitute parts should prioritize active product status and regulatory compliance:

MAX1480ACPI+ is the direct successor to the obsolete MAX1480ACPI, offering identical electrical specifications with ROHS3 compliance and active product status. This part is suitable for applications requiring standard DIP packaging in tube format.

MAX1480AEPI+ and MAX1480EACPI+ provide equivalent functionality with ROHS3 compliance and active status. These variants differ only in packaging designation and are interchangeable from an electrical standpoint.

MAX1480EAEPI+ maintains full electrical equivalence with the highest available inventory (30,100 units), providing supply chain stability for high-volume production requirements.

All substitute parts are manufactured by Analog Devices Inc./Maxim Integrated and carry REACH Unaffected status with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can MAX1480ACPI+ directly replace MAX1480ACPI in existing designs?

A: Yes. MAX1480ACPI+ maintains identical electrical specifications, supply voltage range, operating temperature range, data rate, and 28-DIP package configuration. The primary difference is product status (active vs. obsolete) and ROHS3 compliance.

Q: What is the difference between MAX1480ACPI+, MAX1480AEPI+, MAX1480EACPI+, and MAX1480EAEPI+?

A: All four parts are parametrically equivalent with identical electrical and mechanical specifications. Differences exist only in packaging format designation (DIP vs. PDIP variants) and inventory availability. Selection can be based on supplier availability and packaging preference.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MAX1480ACPI+, MAX1480AEPI+, MAX1480EACPI+, MAX1480EAEPI+) are ROHS3 compliant. The original MAX1480ACPI is RoHS non-compliant.

Q: Can these parts be used in applications requiring extended temperature ranges beyond 0°C ~ 70°C?

A: No. All listed parts, including substitutes, are specified for 0°C ~ 70°C operating temperature. Applications requiring extended temperature ranges require alternative component selection.

Q: Is the 28-DIP package compatible with surface-mount PCB designs?

A: No. The 28-DIP package is a through-hole component. Surface-mount applications require alternative transceiver components with SMD packaging.

**Q: What is the significance of the "+" suffix in part numbers?

A: The "+" suffix indicates tube packaging format and typically denotes active product status with current manufacturing compliance standards.
