74ALVC32D,112 Equivalent & Substitute Parts

Part Overview

The 74ALVC32D,112 is a 4-channel 2-input OR gate logic IC manufactured by Nexperia USA Inc. in a 14-SO surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74ALVC series provides low-voltage CMOS logic functionality suitable for applications requiring 1.65V to 3.6V supply operation with minimal quiescent current consumption.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC32D,112 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical logic function (4-channel 2-input OR gate), supply voltage range (1.65V ~ 3.6V), quiescent current (10 µA max), output drive capability (24mA), input logic thresholds, and operating temperature range (-40°C ~ 85°C).

Mechanical Compatibility: All substitute parts use 14-pin surface mount packages with equivalent pinout and footprint dimensions suitable for 14-SOIC form factors.

Compliance Alignment: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory equivalence.

Key Differentiators: Substitute parts are differentiated by manufacturer (Texas Instruments vs. Nexperia), product status (active vs. obsolete), packaging format (tube, cut tape, or tape & reel), and minor propagation delay variations (2.8ns vs. 2ns at 3.3V, 50pF).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: SN74ALVC32D and SN74ALVC32DR are direct functional equivalents manufactured by Texas Instruments with active product status. Both maintain identical electrical specifications and 14-SOIC (0.154", 3.90mm Width) package dimensions. Selection between these two depends on procurement packaging requirements: SN74ALVC32D is supplied in tube format, while SN74ALVC32DR is supplied in cut tape and digi-reel format.

Secondary Substitute: SN74ALVC32NSR is functionally equivalent with active product status but uses a wider 14-SOIC package variant (0.209", 5.30mm Width). This part is suitable only if PCB layout accommodates the increased package width. It is supplied in tape & reel format.

Compliance Assurance: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory equivalence to the obsolete 74ALVC32D,112. Texas Instruments active product status provides long-term availability and supply chain stability compared to the obsolete Nexperia part.

Propagation Delay Consideration: Texas Instruments substitutes exhibit 2.8ns maximum propagation delay at 3.3V and 50pF load, compared to 2ns for the original part. This 0.8ns difference remains within typical system timing margins for general-purpose logic applications.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC32D directly replace 74ALVC32D,112 without PCB modifications?

A: Yes. SN74ALVC32D maintains identical pinout, electrical specifications, and 14-SOIC (0.154", 3.90mm Width) package dimensions. No PCB layout changes are required.

Q: What is the difference between SN74ALVC32D and SN74ALVC32DR?

A: Both parts are electrically and mechanically identical. The difference is packaging format: SN74ALVC32D is supplied in tube format, while SN74ALVC32DR is supplied in cut tape and digi-reel format. Selection depends on assembly line requirements and procurement volume.

Q: Is SN74ALVC32NSR compatible with existing PCB designs?

A: SN74ALVC32NSR uses a wider 14-SOIC package (0.209", 5.30mm Width) compared to the standard 14-SOIC (0.154", 3.90mm Width). PCB footprint compatibility must be verified before substitution. Electrical and functional compatibility is maintained.

Q: Why do Texas Instruments parts show 2.8ns propagation delay instead of 2ns?

A: The 0.8ns difference in maximum propagation delay at 3.3V and 50pF load reflects manufacturing process variations between Nexperia and Texas Instruments. Both values remain within acceptable timing margins for standard logic applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory equivalence to the original 74ALVC32D,112.

Q: What is the supply voltage range for these parts?

A: All parts operate within 1.65V to 3.6V supply voltage range, supporting both 3.3V and lower-voltage applications.
