AM26LS32ACPW Equivalent & Substitute Parts

Part Overview

The AM26LS32ACPW is a 0/4 Receiver interface IC manufactured by Texas Instruments, designed for RS422 and RS423 serial communication protocols. This component is packaged in a 16-TSSOP surface mount configuration and operates within a 4.75V to 5.25V supply voltage range. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute parts must maintain compatibility with the receiver architecture, protocol support, and electrical operating parameters while accommodating packaging and supply voltage variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the AM26LS32ACPW is determined by the following critical parameters: receiver configuration (0/4), protocol support (RS422 minimum), receiver hysteresis characteristics, supply voltage compatibility, operating temperature range, surface mount packaging, and regulatory compliance status.

The AM26LS32ACPWR represents a direct form-fit-function substitute, maintaining identical electrical specifications and package dimensions while differing only in packaging format (Cut Tape/Digi-Reel versus Tube). This part is classified as active and provides continuity for the AM26LS32 base product line.

The MAX3096 series (MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, MAX3096EEE+T) constitutes functional equivalents with protocol expansion capability. These parts support RS422 and RS485 protocols, maintain the 0/4 receiver configuration, and operate as surface mount components in 16-QSOP packaging. However, these substitutes operate within a reduced supply voltage range (3V ~ 3.6V) and feature a lower receiver hysteresis specification (45 mV). The MAX3096EEE+ variants extend the operating temperature range to -40°C ~ 85°C, providing enhanced thermal performance compared to the base AM26LS32ACPW specification.

Engineering Selection Recommendations

Primary Substitute: AM26LS32ACPWR

The AM26LS32ACPWR is the recommended direct replacement for the obsolete AM26LS32ACPW. This part maintains identical electrical specifications, receiver configuration, protocol support, and thermal operating range. The only distinction is packaging format: AM26LS32ACPWR is supplied in Cut Tape (CT) and Digi-Reel format rather than Tube packaging. Both parts are ROHS3 compliant and carry MSL 1 rating. The AM26LS32ACPWR is classified as active, ensuring long-term availability and supply chain continuity.

Secondary Substitutes: MAX3096 Series

The MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, and MAX3096EEE+T represent functional alternatives when supply voltage and operating temperature requirements permit. These parts maintain the 0/4 receiver configuration and RS422 protocol compatibility. Selection within the MAX3096 series depends on packaging preference (Tube versus Cut Tape/Digi-Reel) and operating temperature requirements.

For applications requiring standard industrial temperature range (0°C ~ 70°C), either MAX3096CEE+ or MAX3096CEE+T is suitable. For applications requiring extended temperature operation (-40°C ~ 85°C), MAX3096EEE+ or MAX3096EEE+T must be selected.

Critical design consideration: MAX3096 series parts operate at 3V ~ 3.6V supply voltage, which differs from the AM26LS32ACPW specification of 4.75V ~ 5.25V. Substitution with MAX3096 variants requires circuit redesign to accommodate the reduced supply voltage range. Additionally, receiver hysteresis is specified at 45 mV for MAX3096 parts versus 50 mV for AM26LS32ACPW, which may affect noise margin characteristics in specific applications.

All substitute parts are ROHS3 compliant and carry MSL 1 rating, maintaining regulatory equivalence with the original component.

Frequently Asked Questions (FAQ)

Q: Can AM26LS32ACPWR be used as a direct replacement for AM26LS32ACPW?

A: Yes. The AM26LS32ACPWR is a direct form-fit-function substitute. Both parts share identical electrical specifications, receiver configuration (0/4), protocol support (RS422, RS423), supply voltage range (4.75V ~ 5.25V), operating temperature (0°C ~ 70°C), and package dimensions (16-TSSOP). The only difference is packaging format: AM26LS32ACPWR is supplied in Cut Tape/Digi-Reel format while AM26LS32ACPW was supplied in Tube format. No circuit modifications are required.

Q: What are the key differences between AM26LS32ACPW and MAX3096 series parts?

A: The primary differences are supply voltage range and receiver hysteresis. AM26LS32ACPW operates at 4.75V ~ 5.25V with 50 mV hysteresis, while MAX3096 series parts operate at 3V ~ 3.6V with 45 mV hysteresis. Additionally, MAX3096 parts support RS485 protocol in addition to RS422, whereas AM26LS32ACPW supports RS422 and RS423. Package dimensions also differ: AM26LS32ACPW uses 16-TSSOP (4.40mm width) while MAX3096 uses 16-SSOP (3.90mm width). These differences require circuit redesign for substitution.

Q: Can MAX3096 parts be used in a 5V supply circuit designed for AM26LS32ACPW?

A: No. MAX3096 parts are specified for 3V ~ 3.6V supply voltage and cannot operate at the 4.75V ~ 5.25V range required by AM26LS32ACPW designs. Substitution requires circuit redesign to reduce supply voltage to the 3V ~ 3.6V range.

Q: What is the difference between MAX3096CEE+ and MAX3096EEE+ variants?

A: The primary difference is operating temperature range. MAX3096CEE+ operates from 0°C ~ 70°C, while MAX3096EEE+ operates from -40°C ~ 85°C. All other electrical specifications and package dimensions are identical. Selection depends on the thermal requirements of the target application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—AM26LS32ACPWR, MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, and MAX3096EEE+T—are ROHS3 compliant with MSL 1 rating, maintaining regulatory equivalence with the original AM26LS32ACPW component.

Q: What packaging options are available for substitute parts?

A: AM26LS32ACPWR is available in Cut Tape (CT) and Digi-Reel format. MAX3096CEE+ and MAX3096EEE+ are supplied in Tube packaging. MAX3096CEE+T and MAX3096EEE+T are supplied in Cut Tape (CT) and Digi-Reel format. Selection depends on manufacturing process requirements and inventory management preferences.

Q: Does the 5 mV difference in receiver hysteresis between AM26LS32ACPW and MAX3096 parts affect circuit operation?

A: Receiver hysteresis affects noise margin and signal integrity characteristics. The 5 mV difference (50 mV versus 45 mV) may impact performance in applications with marginal signal quality or high noise environments. Circuit analysis is required to determine if this difference is acceptable for specific applications.
