Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT16373DGG is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Voltage Supply Range: 2.3V ~ 2.7V, 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Package compatibility based on pin count and footprint dimensions

Compliance Requirements:

• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

The substitute parts listed below maintain electrical equivalence through identical logic function, circuit configuration, and voltage specifications. Mechanical substitution is possible where package dimensions and pin assignments are compatible. The 74ALVTH series from Texas Instruments provides direct functional equivalence with variations in independent circuit count and propagation delay characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence with the 74ALVT16373DGG across the specified voltage supply range, operating temperature, and logic function. Selection among substitute options is determined by package and delivery format requirements:

SN74ALVTH16373GR provides direct package compatibility with the original 74ALVT16373DGG, both utilizing the 48-TFSOP package (0.240", 6.10mm Width). This option is suitable for designs where PCB footprint compatibility is required without layout modification.

SN74ALVTH16373VR offers the most compact package option in 48-TFSOP (0.173", 4.40mm Width), applicable for space-constrained designs where reduced package width is beneficial.

SN74ALVTH16373DL and SN74ALVTH16373DLR utilize the 48-BSSOP package (0.295", 7.50mm Width), requiring PCB layout adjustment but offering alternative sourcing channels through different packaging formats (Tube versus Cut Tape & Digi-Reel).

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The improved propagation delay (1ns versus 2ns) in Texas Instruments variants provides enhanced timing performance without compromising functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVTH16373 series parts directly replace the 74ALVT16373DGG without circuit modification?

A: Electrical substitution is direct across all listed Texas Instruments parts due to identical logic function, circuit configuration, voltage specifications, and operating temperature range. Mechanical substitution depends on package selection. SN74ALVTH16373GR maintains identical 48-TFSOP package dimensions and requires no PCB modification. Other variants require footprint adjustment based on their respective package types.

Q: What is the significance of the difference in independent circuits (1 versus 2)?

A: The 74ALVT16373DGG contains 1 independent circuit, while all Texas Instruments substitutes contain 2 independent circuits. This indicates internal circuit architecture differences but does not affect functional equivalence for the 8:8 latch configuration. Both configurations deliver the same logic output characteristics and tri-state control functionality.

Q: How does the propagation delay difference (2ns versus 1ns) affect circuit performance?

A: The Texas Instruments variants exhibit faster propagation delay (1ns) compared to the original Nexperia part (2ns). This represents improved timing performance and is not a limitation for substitution. Circuits designed for the 2ns specification will operate correctly with the faster 1ns parts.

Q: Are there package footprint compatibility considerations?

A: Yes. The 74ALVT16373DGG uses 48-TFSOP (0.240", 6.10mm Width). SN74ALVTH16373GR matches this footprint exactly. SN74ALVTH16373DL and SN74ALVTH16373DLR use 48-BSSOP (0.295", 7.50mm Width), requiring PCB redesign. SN74ALVTH16373VR uses 48-TFSOP (0.173", 4.40mm Width), also requiring layout modification. Verify PCB footprint compatibility before selection.

Q: Do all substitute parts meet the same compliance and environmental standards?

A: All listed substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-40°C ~ 85°C). Compliance certifications are equivalent across all options.

Q: What packaging and delivery format options are available?

A: SN74ALVTH16373DL is supplied in Tube format. SN74ALVTH16373DLR and SN74ALVTH16373VR are available in Cut Tape (CT) & Digi-Reel® format. SN74ALVTH16373GR is supplied in Cut Tape (CT) format. Select based on procurement and assembly requirements.
