Parameter Comparison

Engineering Selection Recommendations

The 74LVC16240ADGG,118 is the designated manufacturer-recommended substitute for the obsolete SN74LVCZ16240ADLR. Both parts maintain identical functional specifications for logic type, element configuration, output type, and current drive capability. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) provides broader thermal operational envelope
• Expanded supply voltage range (1.2V ~ 3.6V versus 2.7V ~ 3.6V) enables operation in lower voltage applications
• ROHS3 compliance and REACH unaffected status maintained
• Identical moisture sensitivity level (MSL 1) and handling requirements

Package geometry differs slightly (48-TFSOP versus 48-BSSOP), requiring PCB layout verification for pin-to-pin compatibility and footprint accommodation.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC16240ADGG,118 directly replace the SN74LVCZ16240ADLR in existing designs?

A: Functional replacement is supported based on identical logic type, element configuration, bit count, output type, and current drive specifications. Physical package dimensions differ (48-TFSOP versus 48-BSSOP), requiring PCB footprint verification before implementation.

Q: What is the primary reason for substitution?

A: The SN74LVCZ16240ADLR is classified as obsolete. The 74LVC16240ADGG,118 maintains functional equivalence while offering active product status for long-term supply availability.

Q: Are there compliance differences between the main part and substitute?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1). No compliance degradation occurs with substitution.

Q: How do the operating temperature ranges differ?

A: The main part operates -40°C ~ 85°C. The substitute extends to -40°C ~ 125°C, providing enhanced thermal performance without reducing the lower temperature limit.

Q: What supply voltage considerations apply?

A: The main part requires 2.7V ~ 3.6V. The substitute accepts 1.2V ~ 3.6V, enabling operation in lower voltage system designs while maintaining full compatibility at the original voltage range.

Q: Are output drive capabilities identical?

A: Yes. Both parts deliver 24mA output high and 24mA output low, ensuring equivalent electrical performance in 3-state buffer applications.
