SN74AC00DBRE4 Equivalent & Substitute Parts

Part Overview

The SN74AC00DBRE4 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-SSOP package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The 74AC00 logic family provides standard NAND gate functionality suitable for digital logic circuits requiring low-power operation across a 2V to 6V supply range.

Substitute Part Grouping Explanation

Substitute parts for the SN74AC00DBRE4 are qualified based on the following criteria:

Functional Equivalence: All substitutes must maintain the same logic type (NAND Gate), circuit count (4 channels), and input configuration (2 inputs per channel).

Electrical Compatibility: Supply voltage range (2V ~ 6V), output current capability (24mA minimum), and propagation delay (8ns @ 5V, 50pF) must be met or exceeded.

Package Compatibility: The original 14-SSOP package may be substituted with 14-TSSOP, which maintains the same pin count and electrical interface while offering a narrower physical footprint (0.173" vs 0.209" width).

Compliance Requirements: All substitutes must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory alignment.

The identified substitutes are grouped into two categories: MFR Recommended parts that provide direct functional replacement with minor package variations, and Active Status alternatives that offer extended operating temperature ranges for enhanced reliability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible): The 74AC00MTC from onsemi provides functional equivalence with identical electrical specifications and operating temperature range. This part maintains obsolete status but offers higher inventory availability (1807 pcs vs 754 pcs). Package transition from 14-SSOP to 14-TSSOP requires PCB layout verification to confirm pin-to-pad compatibility, though both packages maintain identical pin pitch and electrical interface.

For Long-Term Production (Active Status): The MC74AC00DTR2G is the recommended choice for new designs and ongoing production. This part carries Active product status, ensuring continued availability and manufacturer support. The extended operating temperature range (-55°C ~ 125°C) provides enhanced reliability for applications requiring wider environmental tolerance. Quiescent current specification (4 µA maximum) remains within acceptable limits for low-power applications. The 14-TSSOP package offers space optimization benefits on modern PCB designs.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental and hazardous substance directives.

Frequently Asked Questions (FAQ)

Q: Can the 74AC00MTC be used as a direct replacement for the SN74AC00DBRE4?

A: Yes. Both parts share identical electrical specifications, logic configuration, and operating temperature range. The package transition from 14-SSOP to 14-TSSOP requires PCB layout confirmation, as the TSSOP variant has a narrower body width (0.173" vs 0.209"). Pin pitch and electrical interface remain compatible.

Q: What is the primary advantage of the MC74AC00DTR2G?

A: The MC74AC00DTR2G carries Active product status, ensuring long-term availability and manufacturer support. The extended operating temperature range (-55°C to 125°C) accommodates applications requiring wider environmental tolerance compared to the original -40°C to 85°C specification.

Q: Are there package compatibility concerns when substituting 14-SSOP with 14-TSSOP?

A: The 14-TSSOP package maintains identical pin count and pitch as 14-SSOP. The primary difference is body width reduction (0.173" vs 0.209"). PCB footprint verification is required to confirm pad-to-pin alignment, but electrical interface compatibility is maintained.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original SN74AC00DBRE4 regulatory classification.

Q: Which substitute should be selected for new product designs?

A: The MC74AC00DTR2G is the recommended choice for new designs due to Active product status, extended temperature range, and higher inventory availability (20300 pcs). This ensures design longevity and supply chain stability.
