SN74ACT11PW Equivalent & Substitute Parts

Part Overview

The SN74ACT11PW is a 3-channel AND gate logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited availability. The part operates within the 74ACT logic family, providing standard AND gate functionality with three independent 3-input channels. Identifying equivalent substitute parts is necessary due to the Last Time Buy status and to ensure continued supply chain access for new designs and production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74ACT11PW is determined by strict equivalence across the following critical parameters:

• Logic function: AND Gate with 3 channels and 3 inputs per channel
• Electrical specifications: Supply voltage 4.5V ~ 5.5V, quiescent current 2 µA maximum, output current 24mA for both high and low states
• Timing characteristics: Maximum propagation delay of 9.5ns at 5V with 50pF load
• Input logic levels: Low threshold 0.8V, high threshold 2V
• Package format: 14-TSSOP surface mount package with identical physical dimensions
• Compliance: ROHS3 compliant, MSL Level 1

The substitute part SN74ACT11PWR meets all these criteria with identical electrical and mechanical specifications. The primary distinction is packaging format: the main part uses Tube packaging while the substitute uses Tape & Reel (TR) format. Both are surface mount variants of the same base product (74ACT11) and share identical pinout, functionality, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SN74ACT11PWR is a direct functional equivalent to the SN74ACT11PW. Both parts are manufactured by Texas Instruments and share identical electrical performance, timing characteristics, and physical package dimensions. The SN74ACT11PWR is recommended for new designs and ongoing production due to its Active product status, ensuring long-term availability and supply chain continuity.

The primary consideration between these parts is packaging format. The SN74ACT11PW is supplied in Tube packaging, suitable for lower-volume applications and manual handling. The SN74ACT11PWR is supplied in Tape & Reel format, optimized for automated assembly processes and higher-volume production runs. Both formats contain the identical die and provide equivalent electrical performance.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing environments without special moisture control requirements. Selection between these parts should be based on production volume, assembly methodology, and supply chain requirements rather than electrical or functional considerations.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT11PWR be used as a direct replacement for SN74ACT11PW?

A: Yes. Both parts are electrically and functionally identical. They share the same logic function (3-channel AND gate), electrical specifications, timing characteristics, and 14-TSSOP package dimensions. The only difference is packaging format: Tube versus Tape & Reel.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for lower-volume applications and manual component handling. Tape & Reel packaging is designed for automated pick-and-place assembly equipment and higher-volume production. The components themselves are identical; only the delivery format differs.

Q: Why is SN74ACT11PW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available, but no new production runs are planned. The SN74ACT11PWR, with Active status, is the recommended alternative for continued supply.

Q: Are there any pinout differences between these parts?

A: No. Both SN74ACT11PW and SN74ACT11PWR use identical pinout and are housed in the same 14-TSSOP package. They are pin-for-pin compatible and require no circuit modifications for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL Level 1 rating. They meet identical environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: SN74ACT11PWR is recommended for new designs due to its Active product status and assured long-term availability. It provides identical functionality with better supply chain continuity.
