Trigger Type: Positive edge-triggered
Output Type: Tri-state, non-inverted configuration
Package Type: 20-TSSOP or mechanically compatible surface-mount packages
Voltage Supply Range: Minimum 1.65V to 3.6V compatibility
Operating Temperature: -40°C minimum to 85°C or higher maximum
RoHS Compliance: ROHS3 Compliant

Performance Parameters (Allowable Variation):

Clock Frequency: 100 MHz or higher

Engineering Selection Recommendations

Primary Substitutes (Direct Pin-Compatible, 20-TSSOP Package):

SN74LVC374APWR and SN74LVC374APWT (Texas Instruments) are the preferred direct replacements. Both maintain identical electrical specifications to the original part, including the full 1.65V to 3.6V supply range, tri-state output configuration, and MSL-1 moisture sensitivity rating. These parts are currently in active production status with substantial inventory availability.

Secondary Substitutes (Functional Equivalents, 20-TSSOP Package):

74LVC374AT20-13 (Diodes Incorporated) provides functional equivalence with slightly improved propagation delay (6.8 ns versus 7 ns) but operates with MSL-3 moisture sensitivity, requiring controlled storage conditions. CLVC374AQPWRG4Q1 (Texas Instruments) is qualified to AEC-Q100 automotive standards and suitable for automotive-grade applications, though it specifies a minimum 2V supply voltage and reduced clock frequency (100 MHz).

Alternative Package Substitutes:

SN74LVC374ADBR (20-SSOP package) and SN74LVC374ADGVR (20-TVSOP package) are functionally equivalent alternatives for designs permitting package redesign. Both maintain tri-state output configuration and core electrical specifications but operate within reduced temperature ranges (-40°C to 85°C maximum).

Inventory and Availability:

All recommended active substitutes maintain substantial stock levels (1,630 to 8,300 units), ensuring supply chain continuity. The original Nexperia part, while obsolete, retains 1,118 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can 74LVC374AT20-13 (Diodes) directly replace the Nexperia 74LVC374APW,112?

A: Electrical and functional compatibility is confirmed across all critical parameters. The primary difference is MSL-3 moisture sensitivity versus MSL-1 on the original part. For applications with standard moisture control during storage and handling, this substitution is valid. Extended storage in high-humidity environments without desiccant packaging requires evaluation against your specific MSL requirements.

Q: What is the difference between SN74LVC374APWR and SN74LVC374APWT?

A: Both are Texas Instruments 74LVC374 variants in 20-TSSOP packaging with identical electrical specifications. The primary difference is packaging format: APWR is supplied in tape and reel format, while APWT is supplied in tape and reel format as well. Selection depends on your procurement and assembly process requirements.

Q: Is CLVC374AQPWRG4Q1 suitable for non-automotive applications?

A: Yes. CLVC374AQPWRG4Q1 meets all functional requirements for standard logic applications. The AEC-Q100 automotive qualification indicates enhanced reliability screening and is not restrictive for general-purpose use. The 2V minimum supply voltage specification is the only operational constraint compared to the 1.65V minimum of other variants.

Q: Can I use SN74LVC374ADBR or SN74LVC374ADGVR as direct pin-compatible replacements?

A: These parts are functionally equivalent but use different packages (20-SSOP and 20-TVSOP respectively, versus 20-TSSOP). Direct PCB substitution without layout modification is not possible. These alternatives are suitable only for new board designs or redesign scenarios where package footprint changes are acceptable.

Q: What is the impact of the 74LVC374AT20-13 MSL-3 rating on my supply chain?

A: MSL-3 components require storage in sealed, desiccant-controlled packaging and have a 168-hour floor life after opening. This necessitates controlled handling procedures and shorter shelf life compared to MSL-1 parts. Evaluate your manufacturing environment and storage capabilities before selecting this substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory status of the original Nexperia part.

Q: Which substitute offers the best propagation delay performance?

A: 74LVC374AT20-13 (Diodes) specifies 6.8 ns maximum propagation delay at 3.3V with 50pF load, compared to 7 ns for most other variants. This represents a marginal 0.2 ns improvement and is not typically significant for standard logic applications.
