Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC374AT20-13 are qualified based on the following critical parameters:

• Functional Type: D-Type flip-flop with 8-bit configuration and positive edge triggering
• Package Compatibility: 20-TSSOP surface mount package (0.173", 4.40mm Width)
• Electrical Compatibility: Supply voltage range, output drive capability (24mA), and quiescent current (10 µA)
• Trigger Mechanism: Positive edge triggering
• Compliance: RoHS3 compliance and REACH unaffected status

The identified substitutes maintain these core parameters while allowing for variations in clock frequency, propagation delay, and output type configuration. All substitutes are qualified for the same application space and PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

74LVC574AT20-13 (Diodes Incorporated): This part is functionally equivalent with identical supply voltage range and operating temperature specifications. It maintains ROHS3 compliance and is suitable for direct substitution in applications where the 74LVC374AT20-13 is specified. The slightly higher propagation delay (7.1ns vs 6.8ns) is within acceptable tolerance for most timing-non-critical applications.

MC74LCX374DTR2G (onsemi): This substitute offers higher clock frequency capability (150 MHz) and superior moisture sensitivity rating (MSL 1). However, the operating temperature range is limited to -40°C to 85°C, which restricts use in extended temperature applications. This part is suitable for commercial and industrial environments where the reduced temperature range is acceptable.

SN74LVC374APWR (Texas Instruments): This part maintains full compatibility with the 74LVC374AT20-13 across all critical parameters including supply voltage and operating temperature. The lower clock frequency (100 MHz) and MSL 1 rating make this suitable for standard industrial applications. This part is appropriate for designs where extended temperature operation is required.

All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC574AT20-13 be used as a direct replacement for the 74LVC374AT20-13?

A: Yes. Both parts share identical supply voltage range (1.65V ~ 3.6V), operating temperature (-40°C ~ 125°C), output drive capability (24mA), quiescent current (10 µA), and 20-TSSOP package. The propagation delay difference (7.1ns vs 6.8ns) is negligible for most applications.

Q: What are the key differences between the MC74LCX374DTR2G and the 74LVC374AT20-13?

A: The MC74LCX374DTR2G operates at a higher clock frequency (150 MHz vs 125 MHz) and has superior moisture sensitivity (MSL 1 vs MSL 3). However, its operating temperature range is limited to -40°C to 85°C compared to -40°C to 125°C for the 74LVC374AT20-13. Selection depends on temperature requirements and moisture exposure conditions.

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

A: Yes. All listed substitutes use the 20-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring identical PCB footprint and mounting compatibility.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original 74LVC374AT20-13 specification.

Q: Which substitute part is best for extended temperature applications?

A: The 74LVC574AT20-13 and SN74LVC374APWR both support the full -40°C to 125°C operating temperature range. The MC74LCX374DTR2G is limited to -40°C to 85°C and is not suitable for extended temperature requirements.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?

A: MSL 1 (Unlimited) indicates the part can be stored indefinitely without moisture baking requirements. MSL 3 (168 Hours) requires moisture baking if the part has been exposed to ambient conditions for more than 168 hours. The MC74LCX374DTR2G and SN74LVC374APWR have superior moisture tolerance for storage and handling.
