Substitute Part Grouping Explanation

Substitute parts for the 74FCT16240ATPVCG4 are classified based on the following substitution criteria:

Parametric Equivalents maintain identical electrical specifications including logic type (Buffer, Inverting), element count (4 elements), bit configuration (4 bits per element), output type (3-State), output current ratings (32mA high, 64mA low), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (48-BSSOP). These parts are direct functional replacements with no design modifications required.

Manufacturer Recommended Substitute (SN74LVCZ16240ADLR) differs in supply voltage range (2.7V ~ 3.6V) and output current specifications (24mA for both high and low), representing a lower-voltage alternative suitable for applications where reduced power consumption and lower voltage operation are acceptable design parameters.

All substitute parts maintain identical package configuration (48-BSSOP), surface mount mounting type, RoHS3 compliance, and MSL rating, ensuring mechanical and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CY74FCT16240ATPVC and SN74ABT16240ADL are parametric equivalents with identical electrical specifications. SN74ABT16240ADL is preferred for new designs due to its active product status, ensuring long-term availability and manufacturing support.

For Lower-Voltage Applications: SN74LVCZ16240ADLR operates at 2.7V to 3.6V supply voltage with reduced output current (24mA for both high and low states). This substitute is suitable only for applications where the lower voltage range and reduced current drive are compatible with system requirements.

All substitute parts maintain ROHS3 compliance and MSL rating 1, meeting environmental and moisture sensitivity requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74LVCZ16240ADLR be used as a direct replacement for 74FCT16240ATPVCG4?

A: SN74LVCZ16240ADLR is not a direct replacement. While it maintains identical logic function, element count, and package configuration, it operates at a different supply voltage range (2.7V ~ 3.6V versus 4.5V ~ 5.5V) and has reduced output current specifications (24mA versus 32mA/64mA). Use this substitute only if your application supports the lower voltage range and reduced current drive.

Q: What is the difference between CY74FCT16240ATPVC and SN74ABT16240ADL?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is product status: SN74ABT16240ADL is active, while CY74FCT16240ATPVC is obsolete. For new designs, SN74ABT16240ADL is recommended due to ongoing manufacturing support.

Q: Are all substitute parts available in the same package?

A: Yes. All listed substitute parts use the 48-BSSOP (0.295", 7.50mm Width) surface mount package, ensuring mechanical compatibility and identical PCB footprint.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited), matching the environmental and moisture sensitivity specifications of the original 74FCT16240ATPVCG4.

Q: Which substitute should I select for a new design?

A: SN74ABT16240ADL is the recommended choice for new designs, as it maintains full parametric equivalence with the original part while offering active product status and assured long-term availability.
