Substitute Part Grouping Explanation

Substitution of the 74ALVT162827DGGS is determined by strict equivalence across the following critical parameters:

• Logic function: Buffer, Non-Inverting
• Element configuration: 2 elements, 10 bits per element
• Output configuration: 3-State output
• Supply voltage range: 2.3V ~ 2.7V and 3V ~ 3.6V
• Output current capability: 12mA high, 12mA low
• Operating temperature range: -40°C ~ 85°C
• Package type: 56-TFSOP surface mount
• Pin count and physical dimensions: 56-pin, 0.240" width

The 74ALVCH162827DGG:1 meets all these criteria and is classified as a parametric equivalent. This substitute maintains identical functional specifications and package compatibility while offering Active product status.

Parameter Comparison

Engineering Selection Recommendations

The 74ALVCH162827DGG:1 is the designated parametric equivalent for the obsolete 74ALVT162827DGGS. Both components are manufactured by Nexperia USA Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and moisture sensitivity classification. The 74ALVCH162827DGG:1 carries Active product status, ensuring continued availability and manufacturer support. Additionally, the substitute part features MSL 1 (Unlimited) compared to MSL 2 (1 Year) for the original part, providing superior moisture protection characteristics for long-term storage and handling.

Both components satisfy ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment for current manufacturing and deployment requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVCH162827DGG:1 be used as a direct replacement for the 74ALVT162827DGGS?

A: Yes. The 74ALVCH162827DGG:1 is a parametric equivalent with identical logic function, pin configuration, electrical specifications, and package dimensions. Direct substitution is supported without circuit modification.

Q: Are there any differences in supply voltage requirements?

A: No. Both parts operate across the same supply voltage ranges: 2.3V ~ 2.7V and 3V ~ 3.6V. Voltage compatibility is maintained.

Q: What is the significance of the different MSL ratings?

A: MSL 2 (1 Year) for the original part requires component use within one year of manufacture. MSL 1 (Unlimited) for the substitute part removes this time constraint, allowing indefinite storage under controlled conditions. This provides greater flexibility in inventory management.

Q: Are the packages physically identical?

A: Yes. Both components use the 56-TFSOP package with 0.240" width and identical pin assignments. PCB layouts and footprints are interchangeable.

Q: Why is the original part classified as Obsolete?

A: The 74ALVT162827DGGS has reached end-of-life status. The 74ALVCH162827DGG:1 represents the active continuation of this product line from the same manufacturer.
