AM26LS32AIDE4 Equivalent & Substitute Parts

Part Overview

The AM26LS32AIDE4 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-SOIC surface mount configuration and operates across the industrial temperature range of -40°C to 85°C with a 4.75V to 5.25V supply voltage.

The AM26LS32AIDE4 carries an Obsolete product status, making it necessary to identify equivalent and substitute components for new designs and ongoing production requirements. Suitable alternatives maintain compatibility through matching electrical specifications, mechanical packaging, and communication protocol support while offering active or last-time-buy availability status.

Engineering Selection Recommendations

For Direct Replacement with Identical Specifications:

AM26LS32AIDR is the primary recommended substitute for the obsolete AM26LS32AIDE4. This part maintains identical electrical characteristics including 50 mV receiver hysteresis, 4.75V to 5.25V supply voltage range, and -40°C to 85°C operating temperature. The AM26LS32AIDR carries Active product status with 8,860 pieces in stock and is available in Cut Tape (CT) & Digi-Reel® packaging format. This component provides the most direct functional equivalence with current availability.

AM26LS32AID serves as a secondary Texas Instruments option, offering identical electrical specifications but with Last Time Buy status. This part is available in Tube packaging with 4,370 pieces in stock. Selection of this component is appropriate for applications where tube packaging is preferred and long-term availability is not a requirement.

For Cross-Manufacturer Substitution:

MAX3096ESE+T is the recommended cross-manufacturer alternative when supply chain flexibility is required. This Analog Devices Inc./Maxim Integrated component maintains the identical 0/4 receiver configuration, 16-SOIC packaging, and -40°C to 85°C operating temperature range. The MAX3096ESE+T supports RS422 protocol (matching the primary protocol of the original part) and carries Active product status with 37,800 pieces in stock. The reduced supply voltage range (3V ~ 3.6V) requires circuit design verification for compatibility with existing power supplies.

MAX3096ESE+ provides equivalent functionality in Tube packaging with 2,100 pieces available, suitable for applications where Cut Tape packaging is not required.

MAX3096CSE+T and MAX3096CSE+ are suitable alternatives for applications operating within the 0°C to 70°C temperature range, offering the same receiver configuration and RS422 support with higher inventory availability (8,546 and 2,000 pieces respectively).

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can AM26LS32AID be used as a direct replacement for AM26LS32AIDE4?

A: Yes. AM26LS32AID provides identical electrical specifications including 50 mV receiver hysteresis, 4.75V to 5.25V supply voltage, and -40°C to 85°C operating temperature. The components are functionally equivalent with differences limited to packaging format (Tube) and product status (Last Time Buy). Pin configuration and protocol support (RS422/RS423) are identical.

Q: What is the primary difference between AM26LS32AIDR and AM26LS32AID?

A: Both parts are electrically identical. The difference is packaging format: AM26LS32AIDR is supplied in Cut Tape (CT) & Digi-Reel® format with Active product status, while AM26LS32AID is supplied in Tube format with Last Time Buy status. AM26LS32AIDR is recommended for new production due to Active availability status.

Q: Can MAX3096ESE+T replace AM26LS32AIDE4 in all applications?

A: MAX3096ESE+T maintains identical receiver configuration (0/4), 16-SOIC packaging, and operating temperature range (-40°C to 85°C). However, the supply voltage range differs: MAX3096ESE+T operates at 3V to 3.6V versus the original part's 4.75V to 5.25V. Circuit design verification is required to confirm power supply compatibility. The receiver hysteresis differs slightly (45 mV versus 50 mV), which may affect noise margin in marginal signal conditions.

Q: What is the significance of the 50 mV versus 45 mV receiver hysteresis difference?

A: Receiver hysteresis defines the voltage difference between the rising and falling threshold levels, affecting noise immunity. The 50 mV hysteresis of AM26LS32AIDE4 and AM26LS32AID/AIDR provides slightly higher noise margin compared to the 45 mV hysteresis of MAX3096 series parts. For applications operating in electrically noisy environments, the original 50 mV specification may be preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (AM26LS32AID, AM26LS32AIDR, MAX3096CSE+, MAX3096CSE+T, MAX3096ESE+, MAX3096ESE+T) carry ROHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance of the original AM26LS32AIDE4.

Q: Which substitute part has the highest inventory availability?

A: MAX3096ESE+T has the highest inventory with 37,800 pieces in stock. This part is available in Cut Tape (CT) & Digi-Reel® packaging and carries Active product status. For applications requiring immediate availability and cross-manufacturer flexibility, this component offers the best supply position.

Q: Can I use MAX3096CSE+ for applications requiring -40°C to 85°C operation?

A: No. MAX3096CSE+ operates within the 0°C to 70°C temperature range, which does not cover the full -40°C to 85°C industrial temperature range of the original AM26LS32AIDE4. For extended temperature applications, use MAX3096ESE+ or MAX3096ESE+T, which support -40°C to 85°C operation.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in two packaging formats: Tube and Cut Tape (CT) & Digi-Reel®. AM26LS32AID and MAX3096CSE+/MAX3096ESE+ are supplied in Tube format. AM26LS32AIDR and MAX3096CSE+T/MAX3096ESE+T are supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on production assembly requirements and inventory management preferences.

Q: Do all substitute parts support both RS422 and RS423 protocols?

A: Texas Instruments parts (AM26LS32AID and AM26LS32AIDR) support both RS422 and RS423 protocols. Analog Devices Inc./Maxim Integrated parts (MAX3096 series) support RS422 and RS485 protocols. For applications requiring RS423 support specifically, use Texas Instruments alternatives.
