TL16C554AIPNR Equivalent & Substitute Parts

Part Overview

The TL16C554AIPNR is an asynchronous communication element UART IC manufactured by Texas Instruments, designed for multi-channel serial communication applications. This quad-channel UART with 16-byte FIFO buffers operates across a 3V to 5.25V supply range and supports data rates up to 1 Mbps. The device is housed in an 80-pin LQFP package (12x12mm) and is actively produced with ROHS3 compliance. Substitute parts are identified when electrical parameters, mechanical specifications, and functional characteristics remain equivalent across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL16C554AIPNR is determined by equivalence across the following critical parameters:

• Electrical Specifications: Supply voltage range (3V to 5.25V), maximum data rate (1 Mbps), and functional features (auto flow control, false start bit detection, modem control)
• Functional Architecture: Four UART channels with 16-byte FIFO buffers
• Mechanical Compatibility: 80-pin LQFP package (12x12mm) for surface mount applications
• Compliance & Certification: ROHS3 compliance, MSL 3 rating, and active product status

The TL16C554APNR meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (TL16C554) and differ only in packaging designation (AIPNR vs. APNR), indicating different tape and reel configurations from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the TL16C554AIPNR and TL16C554APNR are active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on packaging and supply chain considerations rather than functional differences. The AIPNR designation indicates Digi-Reel packaging, while APNR indicates standard cut tape and reel packaging. Both maintain ROHS3 compliance and MSL 3 moisture sensitivity ratings. Component selection should prioritize availability and procurement lead times, as functional performance and board-level compatibility are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TL16C554APNR be used as a direct replacement for TL16C554AIPNR?

A: Yes. Both parts are electrically and mechanically identical. The difference lies in packaging format (Digi-Reel vs. standard cut tape and reel). Pin configuration, electrical performance, and PCB footprint requirements are identical.

Q: What is the difference between AIPNR and APNR packaging designations?

A: AIPNR indicates Digi-Reel packaging, while APNR indicates standard cut tape and reel packaging. Both formats contain the same die and deliver identical electrical performance. The choice depends on assembly equipment compatibility and procurement preferences.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity ratings. Regulatory and environmental certifications are equivalent.

Q: What are the critical parameters for UART IC substitution?

A: Channel count, FIFO depth, maximum data rate, supply voltage range, package type, and pin configuration must match. For the TL16C554 series, all these parameters are identical between AIPNR and APNR variants.

Q: Can these parts be used interchangeably in high-speed serial communication applications?

A: Yes. Both parts support identical maximum data rates (1 Mbps) and feature sets including auto flow control, false start bit detection, and modem control. Functional performance in serial communication circuits is equivalent.
