Engineering Selection Recommendations

For Active Production Requirements:

Select SN74LVC16245ADGGR (Texas Instruments) as the primary substitute. This part maintains active product status, extends voltage supply range to 1.65V ~ 3.6V, preserves the full -40°C to 125°C operating temperature specification, and carries ROHS3 compliance with MSL 1 rating. Inventory availability is substantial at 65,188 units.

For Cost-Optimized Applications with Reduced Temperature Range:

74LCX16245MTDX (onsemi) provides an active alternative with high inventory (32,954 units). This part operates within 2V ~ 3.6V supply range and -40°C to 85°C temperature range. MSL rating of 2 (1 Year) requires standard moisture control during storage and handling.

For Renesas-Preferred Supply Chain:

74LVC16245APAG8 or 74LVCH16245APAG8 (Renesas Electronics Corporation) offer active status with ROHS3 compliance and MSL 1 rating. Both support 2.7V ~ 3.6V supply voltage and -40°C to 85°C operating temperature. Tape & Reel packaging is available for automated assembly.

For IDT-Based Designs:

74LVC162245APAG (IDT) provides active status with 2.7V ~ 3.6V supply range. Note that output current specifications include dual ratings (12mA/24mA options), requiring circuit-level verification of current requirements.

Obsolete Part Alternatives:

74LCX16245MTD (onsemi) carries Last Time Buy status with 15,517 units in stock. This represents a transitional option for designs requiring extended procurement windows before full migration to active alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC16245ADGG,112 be directly replaced with SN74LVC16245ADGGR?

A: Yes. Both parts share identical functional specifications: 2-element, 8-bit non-inverting transceiver with 3-state output, 24mA output current, 48-TFSOP package, and -40°C to 125°C operating temperature. SN74LVC16245ADGGR extends the lower voltage limit to 1.65V, providing enhanced compatibility with lower-voltage systems.

Q: What is the voltage compatibility difference between Category A and Category B substitutes?

A: Category A substitutes (SN74LVC16245ADGGR, 74LVC16245APAG, 74LVCH16245APAG) support supply voltages down to 1.65V or 2.7V, matching or exceeding the original 1.2V specification. Category B substitutes (74LCX16245MTD, 74LCX16245MTDX) operate from 2V minimum, requiring circuit verification that system voltage does not drop below 2V during operation or power sequencing.

Q: Are there temperature rating implications when substituting?

A: The original 74LVC16245ADGG,112 operates to 125°C. Most active substitutes (74LVC16245APAG, 74LVCH16245APAG, 74LCX16245MTDX) are rated to 85°C maximum. For applications requiring 125°C operation, select SN74LVC16245ADGGR or SN74LVC16245ADGG (Texas Instruments), which maintain the full temperature range.

Q: What packaging options are available for these substitutes?

A: All substitutes are available in 48-TFSOP surface mount package. Packaging variants include Tube, Cut Tape (CT) & Digi-Reel, and Tape & Reel (TR). Verify packaging format compatibility with your assembly process before procurement.

Q: Does MSL rating affect part selection?

A: MSL 1 (Unlimited) parts require no special moisture control. MSL 2 (1 Year) parts, such as 74LCX16245MTD and 74LCX16245MTDX, must be stored in controlled humidity environments and used within one year of packaging. Verify your supply chain moisture management capabilities before selecting MSL 2 alternatives.

Q: Are all substitutes RoHS3 compliant?

A: All listed active substitutes carry ROHS3 compliance certification. The IDT part (74LVC162245APAG) does not specify RoHS status in available documentation. Confirm RoHS compliance requirements with your procurement and regulatory teams before final selection.

Q: Can 74LVC162245APAG be used as a direct substitute despite different part numbering?

A: 74LVC162245APAG shares identical functional specifications and package format. However, the base product number differs (74LVC162245 vs. 74LVC16245), indicating potential internal architecture variations. Circuit-level verification is required before substitution in production designs.
