Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ALVT16827DGGY is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 10
• Output Type: 3-State
• Current - Output High, Low: 32mA, 64mA
• Voltage - Supply: 2.3V ~ 2.7V, 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 56-TFSOP (0.240", 6.10mm Width)
• Mounting Type: Surface Mount

The SN74ALVTH162827GR from Texas Instruments meets all these electrical and mechanical parameters, establishing it as a parametric equivalent. Differences in packaging format (Tape & Reel vs. Cut Tape) and moisture sensitivity level do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVTH162827GR is a direct parametric equivalent for the 74ALVT16827DGGY. Both devices are classified as obsolete and carry ROHS3 compliance with REACH unaffected status. The Texas Instruments part offers improved moisture sensitivity characteristics (MSL 1 vs. MSL 2), which may provide extended shelf life and reduced handling constraints in storage and logistics environments. Both parts are suitable for applications requiring buffer functionality with 3-state output in the specified voltage and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVTH162827GR directly replace the 74ALVT16827DGGY in existing designs?

A: Yes. Both parts share identical electrical specifications including logic type, element count, bit width, output type, current ratings, supply voltage range, and operating temperature. The 56-TFSOP package dimensions are identical, enabling direct PCB-level substitution.

Q: What is the difference between the 74ALVT and 74ALVTH series designations?

A: The series designation reflects manufacturer-specific product lines. The 74ALVTH is the Texas Instruments equivalent series to the Nexperia 74ALVT series. Both series maintain compatible electrical and mechanical specifications for this buffer device.

Q: Does the packaging format difference (Cut Tape vs. Tape & Reel) affect substitution?

A: No. Packaging format differences relate to supply and handling methods only. The physical component and its electrical performance remain identical. Selection between Cut Tape and Tape & Reel depends on procurement volume and assembly line requirements, not functional compatibility.

Q: What does the improved MSL rating on the Texas Instruments part mean?

A: The SN74ALVTH162827GR carries MSL 1 (Unlimited shelf life) compared to MSL 2 (1 Year) for the Nexperia part. This indicates lower moisture absorption characteristics, reducing the risk of moisture-related failures during storage and reducing the need for controlled humidity storage conditions.

Q: Are both parts suitable for new designs?

A: Both parts are classified as obsolete. For new designs, consultation with component suppliers regarding long-term availability and consideration of active alternative buffer devices is recommended.
