MAX3467EPA Equivalent & Substitute Parts

Part Overview

The MAX3467EPA is a 1/1 transceiver IC designed for full-duplex RS422 and RS485 serial communication applications. This device operates at 40 Mbps data rate with a 50 mV receiver hysteresis, housed in an 8-DIP through-hole package. The MAX3467EPA is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3467EPA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Transceiver configuration: 1/1 full-duplex RS422/RS485 protocol support
• Package type: 8-DIP (0.300", 7.62mm) through-hole mounting
• Supply voltage range: 4.75V – 5.25V
• Operating temperature range: -40°C to +85°C
• Receiver hysteresis: 50 mV (or equivalent specification)

Identified Substitutes:

The MAX3467EPA+ qualifies as a direct substitute. This part maintains identical electrical specifications and package configuration while offering active product status and RoHS3 compliance.

The LTC490IN8#PBF is listed as a manufacturer-recommended alternative. While it meets the core substitution criteria (1/1 transceiver, RS422/RS485 protocol, 8-DIP package, identical supply voltage and temperature range), it specifies a receiver hysteresis of 70 mV, which differs from the 50 mV specification of the main part.

Parameter Comparison

Engineering Selection Recommendations

MAX3467EPA+ (Direct Substitute): This part is the primary replacement for the obsolete MAX3467EPA. It maintains identical electrical and mechanical specifications, including the 50 mV receiver hysteresis and 40 Mbps data rate. The MAX3467EPA+ carries active product status and RoHS3 compliance, making it suitable for new designs and legacy system updates. Inventory availability is 1,071 units.

LTC490IN8#PBF (Alternative Substitute): This part meets the core package and protocol requirements but specifies a 70 mV receiver hysteresis compared to the 50 mV of the original part. The data rate specification is not provided for this device. This part is recommended only when the higher receiver hysteresis specification is acceptable for the application. The LTC490IN8#PBF carries active product status and RoHS3 compliance, with 3,700 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can MAX3467EPA+ be used as a direct replacement for MAX3467EPA? A: Yes. The MAX3467EPA+ maintains identical electrical specifications (50 mV receiver hysteresis, 40 Mbps data rate, 4.75V–5.25V supply, -40°C to +85°C operating range) and package configuration (8-DIP through-hole). The primary difference is product status (active vs. obsolete) and RoHS3 compliance.

Q: What is the difference between MAX3467EPA and LTC490IN8#PBF? A: Both devices are 1/1 full-duplex RS422/RS485 transceivers in 8-DIP packages with identical supply voltage and operating temperature ranges. The LTC490IN8#PBF specifies a 70 mV receiver hysteresis, whereas the MAX3467EPA specifies 50 mV. The data rate for the LTC490IN8#PBF is not specified in available documentation.

Q: Are all substitute parts available in the same packaging? A: The MAX3467EPA+ and LTC490IN8#PBF are both supplied in tube packaging. The original MAX3467EPA packaging specification is not provided. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole package cases.

Q: Which substitute part should be selected for new designs? A: The MAX3467EPA+ is the recommended choice for new designs due to its identical electrical specifications and active product status. The LTC490IN8#PBF may be considered only if the 70 mV receiver hysteresis specification is compatible with system requirements.

Q: Are there RoHS compliance differences between the substitutes? A: Yes. The original MAX3467EPA is RoHS non-compliant. Both substitute parts (MAX3467EPA+ and LTC490IN8#PBF) are RoHS3 compliant, making them suitable for applications with RoHS requirements.
