Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT16373CTPVG is determined by strict alignment of 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
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in propagation delay time (1.5ns vs. 2ns) and output current ratings remain within acceptable tolerance for functional equivalence in latch applications. Differences in product status (active vs. obsolete) and moisture sensitivity levels reflect manufacturing timeline and handling requirements rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

CY74FCT162373ATPVC (Cypress Semiconductor) is the primary recommended substitute, offering active product status with full functional equivalence. This part maintains all critical electrical parameters and is currently in production, ensuring long-term availability and supply chain stability.

For applications requiring exact output current matching (32mA / 64mA), CY74FCT16373ATPVC, CY74FCT16373ATPVCT, and CY74FCT16373CTPVC (all Texas Instruments) provide direct electrical equivalence. These alternatives are suitable for designs where output drive capability is a critical specification.

CY74FCT162373CTPVC (Texas Instruments) is functionally equivalent with reduced output current ratings (24mA / 24mA) and should be selected only when lower drive current is acceptable for the application.

All substitute parts maintain ROHS3 compliance and operate within the specified temperature range. Selection should prioritize CY74FCT162373ATPVC for new designs due to active product status, while obsolete alternatives remain suitable for legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: What makes these parts functionally equivalent to the 74FCT16373CTPVG?

A: All substitute parts share identical logic type (D-Type Transparent Latch), circuit configuration (2 Channel 8:8), output type (tri-state), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package specification (48-BSSOP). These parameters define functional equivalence for latch applications.

Q: Are there differences in propagation delay between the main part and substitutes?

A: The 74FCT16373CTPVG specifies 1.5ns propagation delay, while all substitute parts specify 2ns. This 0.5ns difference is within typical system timing margins for latch circuits and does not affect functional compatibility.

Q: Which substitute part should I select for new designs?

A: CY74FCT162373ATPVC is recommended for new designs due to active product status. This part ensures ongoing availability and manufacturing support.

Q: Do output current ratings affect part selection?

A: Output current ratings vary between substitutes. The 74FCT16373CTPVG provides 32mA high / 64mA low output current. CY74FCT162373ATPVC provides 24mA / 24mA, while CY74FCT16373ATPVC, CY74FCT16373ATPVCT, and CY74FCT16373CTPVC match the original 32mA / 64mA specification. Select based on your circuit's load requirements.

Q: Are all substitutes available in the same package?

A: Yes. All substitute parts are housed in 48-BSSOP (0.295", 7.50mm Width) surface-mount packages with identical pinout and mechanical dimensions, enabling direct board-level replacement.

Q: What is the difference between active and obsolete product status?

A: Active products are in current production with guaranteed long-term availability. Obsolete products are no longer manufactured. CY74FCT162373ATPVC (active) is preferred for new designs, while obsolete alternatives are suitable for legacy system support where inventory exists.

Q: Do moisture sensitivity levels affect compatibility?

A: Moisture sensitivity levels (MSL) reflect handling and storage requirements rather than functional capability. The 74FCT16373CTPVG specifies MSL 3 (168 hours), while most substitutes specify MSL 1 (unlimited). Lower MSL ratings provide more flexible storage conditions but do not affect electrical performance.
