SN74AC00PW NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74AC00PW is a 4-channel 2-input NAND gate logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The 74AC00 series provides standard NAND logic functionality across a wide supply voltage range of 2V to 6V, suitable for digital logic circuits requiring low-power operation and fast propagation delays.

Substitute Part Grouping Explanation

Substitution of the SN74AC00PW is determined by strict equivalence across the following critical parameters: logic type (NAND gate), circuit count (4 channels), input count (2 inputs per gate), supply voltage range (2V ~ 6V), output current capability (24mA), input logic thresholds, propagation delay (8ns @ 5V, 50pF), package type (14-TSSOP), and compliance certifications (ROHS3, REACH Unaffected).

Substitute parts are grouped into three categories based on product status and packaging configuration:

Direct Manufacturer Equivalent - Parts with identical electrical specifications and active product status, differing only in packaging format (Tape & Reel vs. Tube).

Manufacturer Recommended Equivalent - Parts meeting all electrical requirements with extended operating temperature range and active status, packaged in Cut Tape & Digi-Reel format.

Parametric Equivalent - Parts matching all core electrical specifications but with obsolete product status, available in Tube packaging.

Engineering Selection Recommendations

For Active Production (Recommended): SN74AC00PWR or 74AC00MTCX are preferred substitutes. Both maintain active product status with full electrical equivalence to the discontinued SN74AC00PW. SN74AC00PWR is supplied by the original manufacturer (Texas Instruments) in Tape & Reel packaging, ensuring supply chain continuity. 74AC00MTCX is supplied by onsemi in Tape & Reel format with equivalent specifications.

For Extended Temperature Range Applications: MC74AC00DTR2G is the manufacturer-recommended equivalent, offering an extended operating temperature range of -55°C to 125°C compared to the standard -40°C to 85°C range. This part carries active product status and is supplied in Cut Tape & Digi-Reel packaging. Note that quiescent current is specified at 4 µA maximum versus 2 µA for other variants.

For Tube Packaging Requirements: 74AC00MTC provides parametric equivalence in Tube packaging format. This part is currently obsolete and should be selected only when Tube packaging is mandatory and active alternatives are unavailable.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical 14-TSSOP package dimensions, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can SN74AC00PWR be used as a direct replacement for SN74AC00PW?

A: Yes. SN74AC00PWR is electrically identical to SN74AC00PW, with all core parameters matching exactly. The only difference is packaging format: SN74AC00PW is supplied in Tube, while SN74AC00PWR is supplied in Tape & Reel. Both are manufactured by Texas Instruments and are ROHS3 compliant.

Q: What is the difference between 74AC00MTCX and MC74AC00DTR2G?

A: Both are onsemi-manufactured equivalents with active product status. 74AC00MTCX matches all specifications of the original part exactly and is supplied in Tape & Reel packaging. MC74AC00DTR2G extends the operating temperature range to -55°C to 125°C and is supplied in Cut Tape & Digi-Reel packaging. Select MC74AC00DTR2G only if the extended temperature range is required for your application.

Q: Why is 74AC00MTC listed as an option if it is obsolete?

A: 74AC00MTC is included as a parametric equivalent for reference purposes. It maintains all electrical specifications of the original SN74AC00PW and is available in Tube packaging. However, it carries obsolete product status and should only be selected if Tube packaging is a mandatory requirement and active alternatives cannot be used.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 14-TSSOP package with identical dimensions (0.173" width, 4.40mm). No PCB layout modifications are required for any of these substitutes.

Q: What compliance certifications do the substitute parts carry?

A: All substitute parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL) ratings of 1 (Unlimited). Compliance certifications are consistent across all variants.

Q: Which substitute should I select for new designs?

A: For new designs, select SN74AC00PWR (Texas Instruments, active status, Tape & Reel) or 74AC00MTCX (onsemi, active status, Tape & Reel). Both ensure long-term supply availability and active manufacturer support. If extended temperature operation is required, select MC74AC00DTR2G.
