Substitute Part Grouping Explanation

Substitution of the SN74LVCZ240ADGVR is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Inverting configuration
• Element and Bit Configuration: 2 elements with 4 bits per element
• Output Architecture: 3-State output capability
• Output Current Capability: 24mA high and low drive
• Package Footprint: 20-pin TFSOP/TSSOP form factor with 0.173" width and 4.40mm width specification
• Supply Voltage Compatibility: Minimum 2.7V operation requirement

The 74LVC240APW,118 from NXP Semiconductors meets these substitution criteria while offering extended operational characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 74LVC240APW,118 serves as the direct functional equivalent for the obsolete SN74LVCZ240ADGVR. Both components share identical logic architecture, element configuration, output drive capability, and package footprint dimensions. The NXP substitute provides extended supply voltage range (1.2V minimum versus 2.7V) and expanded operating temperature range (-40°C to 125°C versus -40°C to 85°C), offering enhanced operational flexibility without compromising compatibility with existing designs.

Both parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements. The active product status of the 74LVC240APW,118 ensures long-term availability and supply chain continuity compared to the obsolete Texas Instruments part.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC240APW,118 directly replace the SN74LVCZ240ADGVR in existing designs?

A: Yes. Both parts share identical logic type, element count, bit configuration, output type, and output current specifications. The 20-TSSOP and 20-TFSOP packages are footprint-compatible with 0.173" width and 4.40mm width specifications. Pin configuration and functional behavior are equivalent.

Q: What are the differences between the substitute part and the original?

A: The 74LVC240APW,118 offers extended supply voltage range (1.2V to 3.6V versus 2.7V to 3.6V) and wider operating temperature range (-40°C to 125°C versus -40°C to 85°C). The substitute maintains active product status, ensuring ongoing availability.

Q: Are there package compatibility considerations?

A: Both parts use 20-pin TFSOP/TSSOP packages with identical width specifications (0.173", 4.40mm). Surface mount footprints are compatible. Verify PCB layout accommodates the specific package variant during implementation.

Q: What compliance certifications apply to the substitute part?

A: The 74LVC240APW,118 maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original SN74LVCZ240ADGVR.

Q: Why is the original part listed as obsolete?

A: The SN74LVCZ240ADGVR has been discontinued by Texas Instruments. The 74LVC240APW,118 from NXP Semiconductors provides functional continuity for designs requiring buffer inverting logic with 3-state output in the 74LVC family.
