AD7306AN Equivalent & Substitute Parts

Part Overview

The AD7306AN is a 3/3 transceiver IC designed for full-duplex RS232 and RS422 serial communication applications. It integrates three drivers and three receivers in a 24-pin DIP package, operating across the industrial temperature range of -40°C to 85°C with a supply voltage range of 4.75V to 5.25V. The AD7306AN is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7306AN is determined by strict equivalence across the following critical parameters:

• Protocol Support: Both main and substitute parts must support RS232 and RS422 protocols
• Driver/Receiver Configuration: Exact match of 3 drivers and 3 receivers required
• Duplex Mode: Full-duplex operation mandatory
• Receiver Hysteresis: 70 mV specification must be maintained
• Supply Voltage Range: 4.75V to 5.25V compatibility required
• Operating Temperature Range: -40°C to 85°C specification must be met
• Package Type: 24-DIP (0.300", 7.62mm) form factor required for mechanical and electrical compatibility
• Mounting Type: Through-hole mounting compatibility required

The AD7306ANZ qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AD7306ANZ is the direct equivalent substitute for the obsolete AD7306AN. Both parts are manufactured by Analog Devices Inc. and maintain identical electrical and mechanical specifications across all critical parameters including protocol support, driver/receiver configuration, supply voltage, operating temperature range, and package form factor.

The AD7306ANZ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the AD7306ANZ carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and system upgrades.

For applications currently using the AD7306AN, direct replacement with the AD7306ANZ requires no circuit modifications or design changes, as all functional and physical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can the AD7306ANZ be used as a direct replacement for the AD7306AN without circuit modifications?

A: Yes. The AD7306ANZ is electrically and mechanically equivalent to the AD7306AN. All critical parameters including supply voltage, operating temperature range, protocol support, driver/receiver configuration, and 24-DIP package specifications are identical. No circuit modifications are required.

Q: What is the primary reason for substituting the AD7306AN?

A: The AD7306AN is classified as obsolete. The AD7306ANZ is the active equivalent part from Analog Devices Inc., ensuring continued availability and manufacturing support for new designs and system maintenance.

Q: Are there any compliance differences between the AD7306AN and AD7306ANZ?

A: The AD7306ANZ carries ROHS3 compliance certification, meeting current environmental regulations. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited) and share the same ECCN and HTSUS classifications.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in protocol support (RS232/RS422), driver/receiver configuration (3/3), duplex mode (full), receiver hysteresis (70 mV), supply voltage range (4.75V–5.25V), operating temperature range (-40°C to 85°C), and package type (24-DIP 0.300" 7.62mm).

Q: Is the 24-DIP package form factor critical for substitution?

A: Yes. The 24-DIP (0.300", 7.62mm) package is a mandatory substitution criterion. This package type ensures mechanical compatibility with existing PCB layouts and through-hole mounting requirements. Alternative package types are not acceptable substitutes.
