AM26C32CNG4 Equivalent & Substitute Parts

Part Overview

The AM26C32CNG4 is a 0/4 Receiver IC for RS422 and RS423 serial communication protocols, manufactured by Texas Instruments. This component is packaged in a 16-DIP through-hole configuration and operates within a 4.5V to 5.5V supply voltage range. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26C32CNG4 is determined by strict equivalence in the following parameters:

• Protocol support: RS422 and RS423
• Receiver configuration: 0/4 (4 receivers, 0 drivers)
• Receiver hysteresis: 60 mV
• Supply voltage range: 4.5V ~ 5.5V
• RoHS3 compliance
• Base product number: AM26C32

Two substitute parts meet these criteria with variations in packaging and mounting technology:

1. AM26C32CN - Maintains identical DIP packaging with tube packaging option
2. AM26C32IDR - Equivalent electrical specifications with surface-mount SOIC packaging and extended operating temperature range

Parameter Comparison

Engineering Selection Recommendations

For through-hole PCB designs: AM26C32CN provides direct form-factor compatibility with the original AM26C32CNG4, maintaining identical DIP packaging and mounting methodology. Both parts operate within the same temperature and voltage specifications.

For new designs or surface-mount applications: AM26C32IDR is the preferred selection. This part carries active product status from Texas Instruments, ensuring long-term availability and supply chain stability. The extended operating temperature range (-40°C to 85°C) provides broader environmental tolerance compared to the original specification (0°C to 70°C). All electrical parameters remain equivalent to the original part.

Compliance consideration: All three parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IDR replace AM26C32CNG4 in existing through-hole designs?

A: Electrical substitution is valid; however, AM26C32IDR uses surface-mount SOIC packaging rather than through-hole DIP. PCB redesign or adapter solutions are required for mechanical integration into existing through-hole layouts.

Q: What is the functional difference between AM26C32CN and AM26C32IDR?

A: Both parts provide identical RS422/RS423 receiver functionality with 0/4 configuration and 60 mV hysteresis. The primary differences are packaging format (DIP versus SOIC) and operating temperature range. AM26C32IDR supports -40°C to 85°C versus 0°C to 70°C for AM26C32CN.

Q: Why is AM26C32CNG4 discontinued?

A: The original part is discontinued at DiGi Electronics. AM26C32CN remains in obsolete status, while AM26C32IDR maintains active production status from Texas Instruments.

Q: Are all three parts pin-compatible?

A: AM26C32CNG4 and AM26C32CN share identical 16-DIP pinouts. AM26C32IDR uses 16-SOIC packaging with different physical pin layout, requiring PCB redesign for direct substitution.

Q: What inventory status should influence part selection?

A: AM26C32IDR has the highest inventory availability (22,800 pcs) with active product status, providing the most reliable long-term supply option for new procurements.
