74ACT16541SSC Equivalent & Substitute Parts

Part Overview

The 74ACT16541SSC is a Buffer, Non-Inverting logic IC featuring 2 elements with 8 bits per element and 3-state output capability. Manufactured by onsemi in a 48-SSOP package, this component operates across a 4.5V to 5.5V supply voltage range with ±24mA output current capacity. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ACT16541SSC is determined by strict equivalence across the following parameters: logic type (Buffer, Non-Inverting), element count (2), bits per element (8), output configuration (3-State), output current specifications (24mA, 24mA), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), package type (48-BSSOP), and mounting method (Surface Mount). All identified substitutes maintain identical electrical and mechanical specifications, differing only in manufacturer, product status, packaging format, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT16541DLR manufactured by Texas Instruments is the primary substitute for the obsolete 74ACT16541SSC. This part maintains full parametric equivalence while offering active product status and ROHS3 compliance. The Tape & Reel packaging format supports high-volume manufacturing environments.

The 74ACT16541DL, also from Texas Instruments, serves as a secondary substitute with identical electrical specifications. This part carries Last Time Buy status and is supplied in Tube packaging, suitable for lower-volume applications or legacy system maintenance. Both Texas Instruments variants provide ROHS3 compliance and REACH Unaffected certification, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16541DLR directly replace the 74ACT16541SSC in existing designs? A: Yes. Both parts share identical electrical parameters, package dimensions, and pin configurations. The 48-BSSOP package and surface mount specifications are equivalent, enabling direct PCB-level substitution.

Q: What is the difference between 74ACT16541DLR and 74ACT16541DL? A: The primary difference is packaging format. The 74ACT16541DLR is supplied in Tape & Reel format for automated assembly, while the 74ACT16541DL is supplied in Tube format. Electrical specifications and package dimensions are identical. Product status differs: 74ACT16541DLR is Active, while 74ACT16541DL is Last Time Buy.

Q: Why is the 74ACT16541SSC classified as obsolete? A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Substitute parts from active manufacturers ensure continued component availability for system support and new implementations.

Q: Are there compliance differences between the main part and substitutes? A: The Texas Instruments substitutes (74ACT16541DLR and 74ACT16541DL) carry ROHS3 compliance certification, while the onsemi 74ACT16541SSC does not specify this status. Both substitute parts maintain REACH Unaffected status, matching the original component.

Q: Which substitute should be selected for new designs? A: The 74ACT16541DLR is recommended for new designs due to its Active product status and Tape & Reel packaging, which supports modern manufacturing processes and ensures long-term availability.
