SN74AC10PW NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74AC10PW is a 3-channel, 3-input NAND gate logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This component is discontinued at DiGi Electronics but remains available through inventory channels. The part operates across a 2V to 6V supply voltage range with a maximum propagation delay of 7ns at 5V with 50pF load. Due to its discontinued status, identifying functionally equivalent alternatives is necessary for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution for the SN74AC10PW is determined by strict equivalence across the following critical parameters:

Logic function: 3-channel, 3-input NAND gate configuration
Electrical specifications: 2V ~ 6V supply voltage, 2 µA quiescent current, 24mA output drive capability
Timing characteristics: 7ns maximum propagation delay at 5V with 50pF load
Input/output logic levels: 0.9V ~ 1.65V low threshold, 2.1V ~ 3.85V high threshold
Package form factor: 14-TSSOP surface mount package with 0.173" width (4.40mm)
Environmental compliance: ROHS3 compliance, MSL Level 1

The SN74AC10PWR qualifies as a direct substitute based on identical electrical, timing, and package specifications. The only 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 (74AC10 series) with identical pinout and functional performance.

Engineering Selection Recommendations

The SN74AC10PWR is the direct functional equivalent for the discontinued SN74AC10PW. Both parts share identical electrical performance, timing characteristics, and physical package dimensions. The SN74AC10PWR maintains active product status with Texas Instruments, ensuring continued availability and supply chain reliability.

Selection between these parts depends on procurement requirements. The SN74AC10PWR in Tape & Reel format is suitable for automated assembly processes and high-volume production. The original SN74AC10PW in Tube packaging is discontinued but may remain available through existing inventory channels for lower-volume applications or legacy system support.

Both parts meet ROHS3 compliance and carry MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. No additional testing or validation is required when substituting between these variants, as they are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the SN74AC10PWR directly replace the SN74AC10PW in existing designs?

A: Yes. The SN74AC10PWR is electrically and mechanically identical to the SN74AC10PW. Both parts have the same pinout, electrical specifications, timing characteristics, and 14-TSSOP package dimensions. The only difference is packaging format (Tape & Reel versus Tube).

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

A: Tube packaging is used for manual handling and lower-volume applications. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance. Selection depends on assembly process requirements.

Q: Is the SN74AC10PWR still in production?

A: Yes. The SN74AC10PWR maintains active product status with Texas Instruments, ensuring ongoing availability. The original SN74AC10PW is discontinued at DiGi Electronics but may be available through inventory channels.

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

A: No. Both the SN74AC10PW and SN74AC10PWR are ROHS3 compliant with MSL Level 1 rating. They share identical environmental and regulatory compliance status.

Q: What are the critical parameters that define substitution for this NAND gate IC?

A: Substitution is determined by: logic function (3-channel, 3-input NAND gate), supply voltage range (2V ~ 6V), quiescent current (2 µA max), output drive capability (24mA), propagation delay (7ns @ 5V, 50pF), input/output logic thresholds, and 14-TSSOP package form factor. All these parameters must match for direct substitution.

Q: Can I use a different logic IC series as a substitute?

A: No. Substitution is limited to parts with identical logic configuration, electrical specifications, and package form factor. Different logic series (such as 74HC, 74HCT, or 74LVC variants) have different electrical characteristics and are not direct substitutes.
