74ACT00SJ NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACT00SJ is a NAND Gate IC featuring 4 channels with 2 inputs per channel in a 14-SOP surface mount package, manufactured by onsemi. This part is currently obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and design updates. The 74ACT00 logic family provides standard NAND gate functionality suitable for digital logic applications requiring TTL-compatible switching speeds and power consumption characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT00SJ is determined by the following critical parameters:

• Logic family and function (NAND Gate, 4 channels, 2 inputs)
• Electrical specifications (supply voltage 4.5V ~ 5.5V, output current 24mA, propagation delay 9ns @ 5V)
• Input logic levels (Low: 0.8V, High: 2V)
• Operating temperature range (-40°C ~ 85°C minimum)
• Surface mount packaging compatibility

Substitute parts are grouped into two categories:

Direct Substitutes (Electrical and Functional Equivalence): Parts meeting all electrical parameters and operating temperature range of the original 74ACT00SJ.

Similar Substitutes (Functional Equivalence with Parameter Variations): Parts with the same logic function and pin configuration but with relaxed or extended specifications that remain compatible within the application context.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ACT00DR or SN74ACT00NSR (Texas Instruments)

Both parts are active products with ROHS3 compliance, matching electrical specifications, and identical propagation delay characteristics. SN74ACT00DR offers the highest inventory availability (59,099 pcs) and is suitable for standard industrial applications. SN74ACT00NSR provides tape and reel packaging for automated assembly processes.

Extended Temperature Application: SN74ACT00TDRQ1 (Texas Instruments)

This part extends the operating temperature range to -40°C ~ 105°C and includes AEC-Q100 automotive qualification. Select this variant for applications requiring automotive-grade reliability or extended temperature operation beyond standard commercial limits.

Legacy System Compatibility: CD74ACT00M or CD74ACT00M96 (Harris Corporation)

These parts maintain functional compatibility with relaxed quiescent current (4 µA vs. 2 µA) and extended propagation delay (13.2ns vs. 9ns). Both are obsolete but remain suitable for legacy systems where performance margins accommodate the specification variations. Note RoHS non-compliance status for regulatory considerations.

Discontinued Status Consideration: SN74ACT00D

This part is discontinued at DiGi Electronics but maintains full electrical equivalence to the 74ACT00SJ. Availability through alternative distributors may be limited.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT00DR directly replace 74ACT00SJ in existing designs?

A: Yes. Both parts meet identical electrical specifications (supply voltage, quiescent current, propagation delay, and input logic levels). The package footprint is compatible for surface mount assembly, though the physical dimensions differ slightly (0.209" vs. 0.154" width). PCB layout verification is recommended for high-density designs.

Q: What is the difference between SN74ACT00NSR and SN74ACT00DR?

A: Both parts are electrically identical. The primary difference is packaging format: SN74ACT00NSR is supplied in tape and reel (TR) format for automated pick-and-place assembly, while SN74ACT00DR is supplied in cut tape and Digi-Reel format. Select based on assembly process requirements.

Q: Why do CD74ACT00M and CD74ACT00M96 have higher quiescent current and propagation delay?

A: These Harris Corporation parts exhibit relaxed specifications compared to the onsemi 74ACT00SJ and Texas Instruments equivalents. The 4 µA quiescent current and 13.2ns propagation delay remain within acceptable ranges for NAND gate logic applications but represent different manufacturing process characteristics. These parts are suitable only where performance margins accommodate the specification variations.

Q: Is SN74ACT00TDRQ1 suitable for non-automotive applications?

A: Yes. SN74ACT00TDRQ1 is a superset of standard 74ACT00 functionality with extended temperature range (-40°C ~ 105°C) and automotive qualification. It is fully compatible with standard industrial applications and offers enhanced reliability margins at no performance penalty.

Q: What compliance considerations apply to substitute selection?

A: Texas Instruments parts (SN74ACT00NSR, SN74ACT00DR, SN74ACT00D, SN74ACT00TDRQ1) are ROHS3 compliant. Harris Corporation parts (CD74ACT00M, CD74ACT00M96) are RoHS non-compliant. Select based on regulatory requirements for your target market and application.

Q: Are there pin-compatible alternatives outside the 74ACT00 family?

A: Substitution is limited to the 74ACT00 logic family variants listed. Cross-family substitution (such as 74LS00 or 74HCT00) requires full electrical and timing re-qualification due to different logic family characteristics.
