Substitute Part Grouping Explanation

Substitution of the 74HC11DB,112 is determined by the following criteria:

Electrical Compatibility: All substitute parts maintain identical logic function (3-channel AND gate with 3 inputs per channel), supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), and input logic levels. These parameters are non-negotiable for functional equivalence.

Packaging Compatibility: The 74HC11DB,112 uses a 14-SSOP package. Direct package equivalents (14-SSOP) are preferred for PCB layout compatibility. The 14-TSSOP package variant is mechanically similar but has different pitch and width specifications, requiring PCB redesign.

Propagation Delay: The main part specifies 17ns maximum propagation delay at 6V with 50pF load. Substitute parts with equal or faster propagation delay maintain timing compatibility.

Operating Temperature Range: The main part operates from -40°C to 125°C. Substitutes with narrower ranges (-40°C to 85°C) are acceptable for applications not requiring the extended upper temperature limit.

Product Status: The main part is obsolete. Active or recently discontinued alternatives ensure supply chain continuity.

Compliance: All parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and moisture handling compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Replacement (14-SSOP): The SN74HC11ADB from Texas Instruments is the primary substitute. It maintains the 14-SSOP package footprint, ensuring no PCB layout modifications are required. This part is active and ROHS3 compliant. The propagation delay is 14ns, which is faster than the original 17ns specification, providing improved timing margin. The operating temperature range is -40°C to 85°C; applications requiring operation above 85°C must use the original part or the 74HC11PW,118 variant.

For Active Supply with Package Flexibility: The 74HC11PW,118 from Nexperia USA Inc. is an active alternative that maintains all electrical parameters and the full -40°C to 125°C operating range. This part uses the 14-TSSOP package, which requires PCB redesign due to different pitch and width specifications (4.40mm vs. 5.30mm).

For Tape & Reel Packaging: The SN74HC11PWR from Texas Instruments is active and available in Cut Tape and Digi-Reel packaging. It maintains 14-TSSOP package compatibility and all electrical specifications. The operating temperature range is -40°C to 85°C.

Compliance Verification: All recommended substitutes maintain ROHS3 compliance and MSL Level 1 rating, meeting environmental and moisture sensitivity requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC11ADB as a direct replacement for 74HC11DB,112 without PCB modifications?

A: Yes. Both parts use the 14-SSOP package with identical footprint dimensions (0.209" width, 5.30mm). No PCB layout changes are required. The SN74HC11ADB is active and ROHS3 compliant.

Q: What is the difference between 14-SSOP and 14-TSSOP packages?

A: The 14-SSOP package is 5.30mm wide, while the 14-TSSOP package is 4.40mm wide. These are not mechanically interchangeable. Using a 14-TSSOP part requires PCB redesign and new footprint layout.

Q: Does the faster propagation delay of SN74HC11ADB (14ns vs. 17ns) affect compatibility?

A: No. Faster propagation delay improves timing performance and is compatible with designs specified for 17ns. The part meets or exceeds the original specification.

Q: Can I use 74HC11PW,118 if my application requires operation above 85°C?

A: No. The 74HC11PW,118 operates from -40°C to 125°C, matching the original part's temperature range. For applications requiring extended temperature operation, use 74HC11PW,118 or the original 74HC11DB,112. The Texas Instruments variants (SN74HC11ADB, SN74HC11PW, SN74HC11PWR) are limited to -40°C to 85°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory requirements of the original part.

Q: What packaging options are available for active substitutes?

A: Active substitutes are available in the following packaging formats: 14-SSOP (SN74HC11ADB), 14-TSSOP with Tape & Reel (74HC11PW,118), and 14-TSSOP with Cut Tape/Digi-Reel (SN74HC11PWR).
