Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL16C554IPNR is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 4 independent UART channels (QUART architecture)
• FIFO Capacity: 16-byte buffers per channel
• Data Rate Support: Maximum 1 Mbps operation
• Supply Voltage Range: 4.75V to 5.25V compatibility
• Control Features: False start bit detection and modem control capability
• Package Specification: 80-LQFP (12x12mm) surface mount form factor
• Environmental Compliance: ROHS3 compliance and MSL 3 rating

The TL16C554PNR qualifies as a parametric equivalent based on identical electrical specifications and mechanical compatibility across all listed parameters.

Parameter Comparison

Engineering Selection Recommendations

The TL16C554PNR serves as the direct parametric equivalent for the obsolete TL16C554IPNR. Both devices maintain identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status: the TL16C554IPNR is classified as Obsolete, while the TL16C554PNR is Active, ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and identical MSL ratings, confirming environmental and reliability equivalence. The packaging difference (Tube versus Tape & Reel) reflects distribution format only and does not affect component functionality or performance.

Frequently Asked Questions (FAQ)
