Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT162373CTPVG is determined by the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2 Channel 8:8
• Output Type: Tri-State
• Voltage - Supply: 4.5V ~ 5.5V
• Package / Case: 48-BSSOP
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C

Substitute parts must maintain compatibility across these core electrical and mechanical specifications. Variations in propagation delay time (1.5ns to 2ns) and output current ratings (24mA to 64mA) are permissible within the 74FCT logic family, as these represent performance enhancements rather than functional incompatibilities. Parts sharing the base product number 74FCT162373 or 74FCT16373 with identical package and pin configurations qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the 74FCT162373CTPVG, the following selection criteria apply:

Active Product Status Priority: CY74FCT162373ATPVC and 74FCT162373ATPVCT are classified as active products and represent the preferred substitutes for new designs and long-term system support. These parts maintain identical electrical specifications and package compatibility while ensuring ongoing manufacturer support and availability.

Obsolete Product Alternatives: CY74FCT162373CTPVC, CY74FCT16373ATPVC, CY74FCT16373ATPVCT, and CY74FCT16373CTPVC are functionally equivalent but carry obsolete status. These alternatives are suitable for legacy system maintenance where existing inventory exists or where short-term availability is confirmed.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards. The MSL rating differential (3 versus 1) reflects improved moisture handling in substitute parts, providing enhanced reliability in storage and handling scenarios.

Performance Characteristics: Substitute parts from the 74FCT16373 base product number exhibit enhanced output current ratings (32mA/64mA versus 24mA/24mA), providing superior drive capability while maintaining backward compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CY74FCT162373ATPVC directly replace 74FCT162373CTPVG in existing designs?

A: Yes. CY74FCT162373ATPVC maintains identical logic type, circuit configuration, output type, supply voltage range, operating temperature, and 48-BSSOP package specifications. The active product status of CY74FCT162373ATPVC makes it the primary recommended substitute.

Q: What is the significance of the propagation delay difference between 1.5ns and 2ns?

A: The 0.5ns difference represents a performance variation within the 74FCT logic family. This delay differential does not affect functional compatibility in standard latch applications and remains within acceptable timing margins for most circuit implementations.

Q: Are parts with base number 74FCT16373 compatible with 74FCT162373 designs?

A: Yes, with output current consideration. Parts designated 74FCT16373 (CY74FCT16373ATPVC, CY74FCT16373ATPVCT, CY74FCT16373CTPVC) provide enhanced output current ratings (32mA/64mA) and maintain identical pin configuration and functional operation. These represent functional upgrades suitable for direct substitution.

Q: What does MSL rating 3 versus MSL rating 1 mean for component handling?

A: MSL 3 (168 Hours) indicates the component can remain exposed to moisture for up to 168 hours before soldering. MSL 1 (Unlimited) indicates no moisture sensitivity limitation. Substitute parts with MSL 1 provide superior handling flexibility and reduced risk of moisture-related failures during storage and assembly.

Q: Which substitute part offers the best long-term availability?

A: 74FCT162373ATPVCT and CY74FCT162373ATPVC, both classified as active products, offer the best long-term availability and manufacturer support. These parts are recommended for new designs and systems requiring extended operational life.
