Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74FCT3244PYG is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 8mA, 24mA
• Voltage - Supply: 2.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

The 74FCT3244APYG meets all these criteria and qualifies as a parametric equivalent. Both parts share identical electrical specifications, thermal characteristics, and physical packaging, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 74FCT3244PYG and 74FCT3244APYG are classified as obsolete products. Selection between these parts should be based on availability and compliance requirements. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments. The 74FCT3244APYG is available in Tube packaging with 1172 pieces in stock, compared to 1077 pieces for the 74FCT3244PYG. For applications requiring this logic buffer function, either part provides equivalent electrical and mechanical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT3244APYG directly replace the 74FCT3244PYG in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, supply voltage range, operating temperature range, and 20-SSOP surface mount packaging. Direct substitution is supported without circuit modification.

Q: What determines compatibility between these buffer ICs?

A: Compatibility is established through matching logic type (non-inverting buffer), element count (2), bit count per element (4), output type (3-state), current ratings (8mA high, 24mA low), supply voltage (2.7V to 3.6V), temperature range (-40°C to 85°C), and physical package (20-SSOP). All these parameters are identical between the two parts.

Q: Are there packaging differences between these parts?

A: The 74FCT3244PYG and 74FCT3244APYG both use 20-SSOP surface mount packaging with identical physical dimensions (0.209" width, 5.30mm). The primary difference is supplier packaging format (Tube for the APYG variant), which does not affect circuit performance or PCB assembly compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 74FCT3244PYG and 74FCT3244APYG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: Why is the 74FCT3244PYG marked as obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. The 74FCT3244APYG, also obsolete, serves as an equivalent alternative for applications requiring this specific buffer function. Both parts remain available through existing inventory channels.
