Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC1G175DBVRG4 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Base product number: 74LVC1G175
• Function: Reset-capable D-type flip-flop
• Type: Single-element, 1-bit configuration
• Output type: Non-inverted
• Trigger type: Positive edge
• Supply voltage range: 1.65V ~ 5.5V (minimum requirement)
• Operating temperature: -40°C ~ 125°C
• RoHS compliance: ROHS3 Compliant

Acceptable Variations:

• Clock frequency: 175 MHz or higher
• Max propagation delay: 4 ns or lower (at 5V, 50pF load)
• Output current: 32 mA or higher
• Quiescent current: 10 µA or lower
• Input capacitance: 3 pF or lower
• Package type: SOT-23-6 (primary) or alternative surface mount packages (SC-74, SOT-457, 6-TSSOP) with compatible pinout
• Product status: Active preferred; discontinued acceptable if electrically equivalent

Substitutes are grouped into two categories: direct package equivalents (SOT-23-6) and alternative package equivalents (SC-74/SOT-457, 6-TSSOP/SOT-363) that maintain electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Package Equivalents (SOT-23-6):

SN74LVC1G175DBVR and SN74LVC1G175DBVT are the primary substitutes for the 74LVC1G175DBVRG4. Both are manufactured by Texas Instruments, maintain the identical SOT-23-6 package footprint, and are currently in active production status. These parts are electrically compatible with the original device across all critical parameters. The SN74LVC1G175DBVR offers superior inventory availability (113,300 units) compared to SN74LVC1G175DBVT (2,800 units). Both parts exhibit a maximum propagation delay of 5 ns at 5V with 50pF load, which is 1 ns longer than the original specification but remains within acceptable operational margins for most applications. All three parts maintain ROHS3 compliance and MSL Level 1 rating.

Alternative Package Equivalents (SC-74/SOT-457 and 6-TSSOP/SOT-363):

The Nexperia USA Inc. parts 74LVC1G175GV,125, 74LVC1G175GV-Q100H, and 74LVC1G175GW,125 provide functional equivalence with improved electrical performance. These devices operate at 200 MHz clock frequency (versus 175 MHz) and deliver 4 ns maximum propagation delay at 5V with 50pF load, matching the original specification. The trade-off is increased quiescent current (40 µA versus 10 µA) and reduced input capacitance (2.5 pF versus 3 pF). These parts require PCB layout modifications due to different package geometries: 74LVC1G175GV,125 and 74LVC1G175GV-Q100H use SC-74/SOT-457 packaging, while 74LVC1G175GW,125 uses 6-TSSOP/SOT-363 packaging. The 74LVC1G175GV-Q100H variant includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components. All Nexperia parts maintain ROHS3 compliance and MSL Level 1 rating.

Selection Criteria:

For direct board-level replacement without layout modification, select SN74LVC1G175DBVR or SN74LVC1G175DBVT. For applications where improved propagation delay performance is required and PCB redesign is feasible, select the Nexperia alternatives. For automotive applications, 74LVC1G175GV-Q100H is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74LVC1G175DBVRG4 with SN74LVC1G175DBVR without PCB modifications?

A: Yes. Both parts use the SOT-23-6 package with identical pinout and footprint. No PCB layout changes are required. The electrical performance is compatible across all critical parameters including supply voltage range, operating temperature, and output drive capability.

Q: What is the difference between the Texas Instruments SOT-23-6 parts and the Nexperia SC-74/SOT-457 parts?

A: The primary differences are package geometry and quiescent current. The Nexperia parts offer faster clock frequency (200 MHz versus 175 MHz) and lower propagation delay (4 ns versus 5 ns for the TI DBVR/DBVT variants), but require PCB layout modifications due to different package dimensions. Nexperia parts also consume higher quiescent current (40 µA versus 10 µA).

Q: Is the 1 ns increase in propagation delay from the TI DBVR/DBVT parts significant?

A: The 1 ns difference (5 ns versus 4 ns at 5V, 50pF) is typically negligible for most digital logic applications. Timing-critical designs should verify that the 5 ns specification remains within system timing margins. For applications with tight timing constraints, the Nexperia alternatives with 4 ns propagation delay are recommended.

Q: What does the "Q100H" designation in 74LVC1G175GV-Q100H indicate?

A: The Q100H designation indicates AEC-Q100 automotive qualification. This part meets automotive industry reliability and quality standards and is suitable for automotive applications requiring qualified components.

Q: Can I use the 6-TSSOP package variant (74LVC1G175GW,125) as a substitute?

A: Yes, electrically the 6-TSSOP variant is fully compatible. However, the package footprint differs from SOT-23-6, requiring PCB layout redesign. The 6-TSSOP package is smaller than SOT-23-6, which may be advantageous for space-constrained designs.

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 status of the original 74LVC1G175DBVRG4.

Q: Which substitute part offers the best inventory availability?

A: SN74LVC1G175DBVR offers the highest inventory availability at 113,300 units, making it the most readily available direct replacement for the discontinued 74LVC1G175DBVRG4.
