SN74AC11PW Equivalent & Substitute Parts

Part Overview

The SN74AC11PW is a 3-channel AND gate logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This device implements three independent 3-input AND gates in a single integrated circuit, operating across a 2V to 6V supply voltage range with 8ns maximum propagation delay at 5V with 50pF load.

The SN74AC11PW is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the SN74AC11PW is determined by strict equivalence across the following critical parameters:

Logic function: 3-channel AND gate with 3 inputs per channel
Electrical specifications: 2V ~ 6V supply voltage, 8ns propagation delay, 24mA output current capability
Input/output logic levels: 0.9V ~ 1.65V (low), 2.1V ~ 3.85V (high)
Package form factor: 14-TSSOP surface mount package
Compliance certifications: ROHS3 compliance, MSL Level 1

The SN74AC11PWR qualifies as a direct substitute based on identical electrical characteristics, logic configuration, and package specifications. The primary distinction is packaging format: the SN74AC11PW is supplied in tube packaging, while the SN74AC11PWR is supplied in tape and reel format. Both devices are manufactured by Texas Instruments within the 74AC series.

Engineering Selection Recommendations

The SN74AC11PWR is the direct functional equivalent of the SN74AC11PW. Both devices are manufactured by Texas Instruments and maintain identical electrical performance, logic configuration, and physical package specifications.

The SN74AC11PW is discontinued at DiGi Electronics, while the SN74AC11PWR maintains active product status. For new designs and ongoing production requirements, the SN74AC11PWR is the appropriate selection. Both parts carry ROHS3 compliance and MSL Level 1 certification, meeting equivalent environmental and reliability standards.

The distinction between these parts is packaging format only: tube versus tape and reel. This difference affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74AC11PWR directly replace the SN74AC11PW in existing designs?

A: Yes. The SN74AC11PWR is electrically and functionally identical to the SN74AC11PW. Both devices implement three 3-input AND gates with identical electrical specifications, logic levels, propagation delay, and operating temperature range. The 14-TSSOP package pinout and dimensions are identical.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape and reel packaging supplies components on continuous carrier tape wound on reels, designed for automated pick-and-place assembly equipment. Electrical and functional performance is identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74AC11PW and SN74AC11PWR carry identical ROHS3 compliance and MSL Level 1 certification. Environmental and reliability standards are equivalent.

Q: Why is the SN74AC11PW discontinued?

A: The SN74AC11PW is discontinued at DiGi Electronics. The SN74AC11PWR remains in active production as the current supply format for this logic function.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes, provided your assembly process accommodates the packaging format. If your process uses automated pick-and-place equipment, tape and reel format (SN74AC11PWR) is standard. If manual assembly or tube-compatible feeders are used, either format is acceptable. Pin configuration and electrical performance are identical.
