• Output Type: Tri-State, Non-Inverted
• Trigger Type: Positive Edge
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Electrical Performance Criteria:

• Voltage - Supply: 1.65V ~ 3.6V (minimum range requirement)
• Current - Output High, Low: 24 mA, 24 mA
• Clock Frequency: 150 MHz (minimum requirement)
• Max Propagation Delay @ 3.3V, 50pF: ≤ 7 ns
• Current - Quiescent (Iq): ≤ 10 µA

Substitute parts are grouped into two categories: Parametric Equivalents (meeting all criteria) and Similar parts (meeting functional and package criteria with minor electrical parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes):

74LVC374AD,118 (Nexperia USA Inc.) is a parametric equivalent to the 74LVC374AD-Q100J. Both parts share identical electrical specifications, supply voltage range, operating temperature range, and compliance status. This part is suitable for direct substitution in applications where the original part number is unavailable.

SN74LVC574ADWR (Texas Instruments) is a parametric equivalent with superior propagation delay performance (6.8 ns versus 7 ns) and lower quiescent current (1.5 µA versus 10 µA). This part maintains the full supply voltage range (1.65V ~ 3.6V) and extended operating temperature range (-40°C ~ 125°C). The improved electrical characteristics make this part suitable for direct substitution.

Similar Parts (Functional Equivalents with Parameter Variations):

CLVC374AQDWRG4Q1 (Texas Instruments) is functionally equivalent with AEC-Q100 automotive qualification. The part exhibits reduced clock frequency (100 MHz versus 150 MHz) and increased propagation delay (8.5 ns versus 7 ns). The supply voltage range is narrower (2V ~ 3.6V versus 1.65V ~ 3.6V). This part is suitable for applications where the reduced performance specifications are acceptable.

SN74LVC374ADW (Texas Instruments) is functionally equivalent with reduced clock frequency (100 MHz versus 150 MHz) and matching propagation delay (7 ns). The operating temperature range is reduced to -40°C ~ 85°C. This part is suitable for applications where the reduced temperature range is acceptable.

MC74LCX374DWR2G (onsemi) is functionally equivalent with matching clock frequency (150 MHz) and increased propagation delay (8.5 ns versus 7 ns). The supply voltage range is narrower (2V ~ 3.6V versus 1.65V ~ 3.6V), input capacitance is higher (7 pF versus 4 pF), and the operating temperature range is reduced to -40°C ~ 85°C. The moisture sensitivity level is MSL 3 (168 Hours) versus MSL 1 (Unlimited). This part is suitable for applications where the reduced specifications and moisture handling requirements are acceptable.

Frequently Asked Questions (FAQ)

Q: Can 74LVC374AD,118 replace 74LVC374AD-Q100J in all applications?

A: Yes. The 74LVC374AD,118 is a parametric equivalent with identical electrical specifications, supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 125°C), and compliance status (ROHS3, MSL 1). Both parts are manufactured by Nexperia USA Inc. and share the same base product number 74LVC374.

Q: What are the key differences between SN74LVC574ADWR and the main part?

A: SN74LVC574ADWR is manufactured by Texas Instruments and uses a different base product number (74LVC574 versus 74LVC374). However, it maintains parametric equivalence with superior propagation delay (6.8 ns versus 7 ns) and lower quiescent current (1.5 µA versus 10 µA). The supply voltage range and operating temperature range are identical.

Q: Is CLVC374AQDWRG4Q1 suitable for automotive applications?

A: Yes. CLVC374AQDWRG4Q1 carries AEC-Q100 automotive qualification. However, the part exhibits reduced clock frequency (100 MHz versus 150 MHz) and increased propagation delay (8.5 ns versus 7 ns). The supply voltage range is narrower (2V ~ 3.6V). These parameter variations must be evaluated against application requirements.

Q: What is the impact of the narrower supply voltage range in MC74LCX374DWR2G?

A: MC74LCX374DWR2G operates across 2V ~ 3.6V versus the main part's 1.65V ~ 3.6V. Applications requiring operation below 2V supply voltage cannot use this substitute. Additionally, this part has higher input capacitance (7 pF versus 4 pF) and reduced operating temperature range (-40°C ~ 85°C).

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts are available in 20-SOIC (0.295", 7.50mm Width) surface mount packaging, matching the main part's mechanical specifications.

Q: What is the significance of MSL rating differences?

A: The main part and most substitutes carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. MC74LCX374DWR2G carries MSL 3 (168 Hours), requiring controlled moisture exposure during storage and limiting shelf life to 168 hours after moisture absorption. This affects supply chain handling and storage procedures.

Q: Can SN74LVC374ADW be used in applications requiring extended temperature operation?

A: No. SN74LVC374ADW operates across -40°C ~ 85°C, which is narrower than the main part's -40°C ~ 125°C range. Applications requiring operation above 85°C cannot use this substitute.
