AM26LS32AMDREP Equivalent & Substitute Parts

Part Overview

The AM26LS32AMDREP is a 0/4 Receiver IC for RS422 and RS423 protocols, manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The part operates across an extended temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V and features 50 mV receiver hysteresis.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26LS32AMDREP is determined by the following critical parameters:

• Package compatibility: 16-SOIC form factor (0.154", 3.90mm Width)
• Functional equivalence: 0/4 Receiver configuration
• Protocol support: RS422 and/or RS423 capability
• Supply voltage range: Compatibility with 4.5V to 5.5V operation
• Receiver hysteresis: Acceptable range for signal integrity
• Operating temperature range: Support for extended or standard industrial ranges
• RoHS and regulatory compliance: ROHS3 compliance and REACH unaffected status

The substitute parts identified fall into two categories: direct protocol equivalents (RS422/RS423 support) and protocol-extended equivalents (RS422/RS485 support). All substitute parts maintain the 16-SOIC package and surface mount mounting type. Voltage supply ranges and operating temperature ranges vary among substitutes, requiring application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

ST26C32ABDR is the primary substitute for applications requiring RS422/RS423 protocol support with 4.5V to 5.5V supply voltage operation. This part maintains voltage compatibility with the original AM26LS32AMDREP, operates across -40°C to 85°C, and is actively produced by STMicroelectronics with full ROHS3 compliance and unlimited moisture sensitivity rating.

MAX3096ESE+T is suitable for applications where RS422/RS485 protocol flexibility is acceptable and supply voltage can be adjusted to 3V to 3.6V. This part offers extended operating temperature range (-40°C to 85°C), active product status, and highest inventory availability (37,800 units). The MAX3096 series from Analog Devices Inc./Maxim Integrated provides protocol extension beyond the original RS423 specification.

SP26LV432CN-L is applicable for high-speed applications requiring 50Mbps data rate capability with 3.3V supply operation. This part carries Last Time Buy status and should be evaluated for long-term availability constraints. Moisture sensitivity level is rated at 2 (1 Year), requiring controlled storage conditions.

MAX3096CSE+ and MAX3096CSE+T variants provide identical electrical specifications to MAX3096ESE+ and MAX3096ESE+T respectively, with the primary difference being operating temperature range (0°C to 70°C versus -40°C to 85°C). Selection between these variants depends on application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX3096 series parts directly replace AM26LS32AMDREP in existing designs?

A: MAX3096 series parts are functionally compatible as 0/4 receivers in 16-SOIC packages. However, supply voltage must be adjusted from 4.5V-5.5V to 3V-3.6V. Protocol support extends to RS485, which is compatible with RS422 applications. Operating temperature range differs (0°C to 85°C depending on variant versus -55°C to 125°C original). Application-specific validation is required.

Q: What is the difference between MAX3096CSE+, MAX3096CSE+T, MAX3096ESE+, and MAX3096ESE+T?

A: All four variants share identical electrical specifications (0/4 receiver, RS422/RS485, 45 mV hysteresis, 10Mbps data rate, 3V-3.6V supply). The differences are: CSE+ and CSE+T operate 0°C to 70°C; ESE+ and ESE+T operate -40°C to 85°C. Packaging differs: CSE+/ESE+ use Tube; CSE+T/ESE+T use Cut Tape (CT) & Digi-Reel®.

Q: Is ST26C32ABDR a voltage-compatible substitute?

A: Yes. ST26C32ABDR maintains 4.5V to 5.5V supply voltage compatibility with AM26LS32AMDREP, eliminating the need for power supply redesign. Both parts support RS422 and RS423 protocols. Operating temperature range is -40°C to 85°C, which is narrower than the original -55°C to 125°C specification.

Q: Why does SP26LV432CN-L have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer (MaxLinear, Inc.) has announced end-of-life for this part. New designs should avoid this part. Existing inventory is available but future procurement will not be possible.

Q: What does Moisture Sensitivity Level (MSL) 2 mean for SP26LV432CN-L?

A: MSL 2 (1 Year) requires that the component be stored in controlled humidity conditions and used within one year of the moisture barrier bag opening. This contrasts with MSL 1 (Unlimited) parts, which have no time-based storage restrictions. Handling procedures must comply with IPC-A-610 standards for MSL 2 components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (MAX3096 series, SP26LV432CN-L, and ST26C32ABDR) are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original AM26LS32AMDREP.

Q: Which substitute offers the highest data rate capability?

A: SP26LV432CN-L supports 50Mbps data rate, compared to 20Mbps for ST26C32ABDR and 10Mbps for MAX3096 series. The original AM26LS32AMDREP does not specify a data rate parameter.
