AM26C32IPW Equivalent & Substitute Parts

Part Overview

The AM26C32IPW is a 0/4 Receiver IC for RS422 and RS423 serial communication protocols, manufactured by Texas Instruments in a 16-TSSOP surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. Finding equivalent substitute parts is necessary to ensure design continuity and long-term supply chain reliability for applications requiring RS422/RS423 receiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM26C32IPW are qualified based on the following critical parameters that must remain constant:

• Protocol support: RS422 and RS423
• Receiver configuration: 0/4 (4 receivers, 0 drivers)
• Receiver hysteresis: 60 mV
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-TSSOP with identical physical dimensions
• Mounting type: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute parts maintain electrical and mechanical compatibility across all specified parameters, ensuring direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the AM26C32IPW. The AM26C32IPWR is the manufacturer-recommended direct replacement from Texas Instruments, currently in Active product status with established supply availability. The ST26C32ABTR from STMicroelectronics provides an alternative from a different manufacturer while maintaining all critical electrical parameters and compliance certifications. Both substitutes are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Selection between substitutes should be based on supply chain availability, lead time, and existing qualification status within your organization.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IPWR be used as a direct replacement for AM26C32IPW? A: Yes. The AM26C32IPWR maintains identical electrical specifications, package dimensions, and functional characteristics. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and active product status versus Last Time Buy.

Q: Is the ST26C32ABTR from STMicroelectronics fully compatible? A: Yes. The ST26C32ABTR meets all critical electrical and mechanical parameters: 0/4 receiver configuration, RS422/RS423 protocol support, 60 mV hysteresis, 4.5V-5.5V supply voltage, -40°C to 85°C operating range, and 16-TSSOP package. The specified 20 Mbps data rate does not conflict with the main part's unspecified data rate parameter.

Q: What are the key parameters that must match for substitution? A: Protocol (RS422/RS423), receiver configuration (0/4), hysteresis (60 mV), supply voltage (4.5V-5.5V), operating temperature (-40°C to 85°C), package type (16-TSSOP), and compliance certifications (ROHS3, REACH).

Q: Does packaging format affect electrical performance? A: No. Packaging format (Tube, Cut Tape, or Digi-Reel) affects handling, storage, and ordering logistics but does not alter electrical or functional characteristics. All three parts are surface mount components in identical 16-TSSOP packages.

Q: Are there any compliance concerns with these substitutes? A: No. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.
