Substitute Part Grouping Explanation

Substitute parts for the PI74FCT241ATQ are identified based on strict electrical and mechanical parameter matching within the 74FCT logic family. The substitution criteria are:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 15mA, 64mA
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 20-SSOP (0.154", 3.90mm Width)
• Supplier Device Package: 20-QSOP

The identified substitutes are manufactured by IDT (Integrated Device Technology Inc) and maintain identical electrical specifications and physical packaging. These parts are classified as either direct manufacturer equivalents or parametric equivalents based on product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The 74FCT244CTQG and 74FCT244ATQG from IDT are direct functional equivalents to the obsolete PI74FCT241ATQ. Both substitute parts maintain identical electrical performance specifications and physical packaging requirements. The 74FCT244CTQG is designated as a direct manufacturer equivalent, while the 74FCT244ATQG is classified as a parametric equivalent.

Selection between the two IDT alternatives should be based on product status and availability. Both parts are currently in active production status, providing long-term supply assurance compared to the obsolete Diodes Incorporated original. The 74FCT244CTQG offers higher inventory availability at 8549 units, while the 74FCT244ATQG maintains 2347 units in stock.

Both substitute parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the original component. The RoHS non-compliance status of the original part should be noted for applications requiring RoHS-compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT244CTQG and 74FCT244ATQG be used interchangeably with the PI74FCT241ATQ?

A: Yes. Both IDT parts maintain identical electrical specifications including output current ratings (15mA, 64mA), supply voltage range (4.75V ~ 5.25V), operating temperature range (-40°C ~ 85°C), and physical packaging (20-QSOP). The functional architecture of 2 elements with 4 bits per element and 3-state output is preserved across all three parts.

Q: What is the difference between the 74FCT244CTQG and 74FCT244ATQG?

A: Both parts are functionally identical with matching electrical and mechanical parameters. The primary distinction is product status: the 74FCT244CTQG is designated as a direct manufacturer equivalent, while the 74FCT244ATQG is a parametric equivalent. Inventory levels differ, with the 74FCT244CTQG offering greater availability.

Q: Are there any compliance or certification differences between the original and substitute parts?

A: All three parts share identical ECCN and HTSUS classifications. The original PI74FCT241ATQ and both IDT substitutes are RoHS non-compliant. Moisture sensitivity level (MSL) for the original is rated at 1 (Unlimited).

Q: Why is the original PI74FCT241ATQ classified as obsolete?

A: The PI74FCT241ATQ has reached end-of-life status with Diodes Incorporated. The active production alternatives from IDT (74FCT244CTQG and 74FCT244ATQG) provide equivalent functionality with ongoing manufacturer support and supply availability.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use the 20-SSOP package with dimensions of 0.154" × 3.90mm width, ensuring direct physical compatibility in PCB layouts and socket applications.
