Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI74FCT162373ATV is determined by the following critical parameters:

• Logic type and circuit configuration (D-type transparent latch, 2 channel 8:8)
• Output type (tri-state)
• Supply voltage compatibility (4.5V ~ 5.5V)
• Package and pinout compatibility (48-BSSOP)
• Operating temperature range (-40°C ~ 85°C)
• Output current drive capability (minimum 24mA)

Substitute parts must maintain identical or superior electrical characteristics within these parameters. Propagation delay time variations are acceptable provided they do not exceed the original specification. Output current drive capability may be equal or greater than the original part.

The identified substitute parts are grouped into two categories based on base product number alignment:

Category 1: PI74FCT162373 Base Number Variants

• 74FCT162373ATPVCT (Cypress Semiconductor)
• CY74FCT162373ATPVC (Cypress Semiconductor)
• CY74FCT162373CTPVC (Texas Instruments)

Category 2: PI74FCT16373 Base Number Variants

• CY74FCT16373ATPVC (Texas Instruments)
• CY74FCT16373ATPVCT (Texas Instruments)
• CY74FCT16373CTPVC (Texas Instruments)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CY74FCT162373ATPVC

The CY74FCT162373ATPVC from Cypress Semiconductor is the recommended primary substitute. This part maintains identical logic type, circuit configuration, output type, supply voltage range, output current specifications, and operating temperature range as the original PI74FCT162373ATV. The propagation delay of 2ns is within acceptable tolerance for most applications. Critically, this part carries Active product status, ensuring ongoing availability and supply chain support. The 48-BSSOP package provides direct mechanical and electrical compatibility.

Secondary Substitutes: CY74FCT162373CTPVC

The CY74FCT162373CTPVC from Texas Instruments provides equivalent electrical specifications to the primary substitute. However, this part is classified as Obsolete, which may limit long-term availability. Selection of this part should be considered only when the primary substitute is unavailable.

Alternative Substitutes: CY74FCT16373 Series

The CY74FCT16373ATPVC, CY74FCT16373ATPVCT, and CY74FCT16373CTPVC parts offer enhanced output current drive capability (32mA/64mA versus 24mA/24mA), providing superior electrical performance. These parts maintain all other critical parameters. However, all three variants are classified as Obsolete. These alternatives are suitable only when enhanced current drive is required and availability can be confirmed.

Compliance Considerations

The CY74FCT162373ATPVC (Active status) does not specify RoHS compliance status in the provided data. The CY74FCT162373CTPVC and CY74FCT16373 series variants are ROHS3 compliant. All substitute parts maintain REACH Unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the CY74FCT162373ATPVC directly replace the PI74FCT162373ATV?

A: Yes. The CY74FCT162373ATPVC maintains identical logic type, circuit configuration, output type, supply voltage range, output current specifications, operating temperature range, and 48-BSSOP package compatibility. The 2ns propagation delay is acceptable for applications designed around the original 1.5ns specification.

Q: What is the difference between the PI74FCT162373 and PI74FCT16373 base product numbers?

A: The base product numbers differ, indicating distinct part variants. Both maintain the same logic type, circuit configuration, and package. The PI74FCT16373 variants provide higher output current drive (32mA/64mA versus 24mA/24mA). Substitution between these base numbers requires verification that the enhanced current drive does not introduce compatibility issues in the target application.

Q: Why is the PI74FCT162373ATV classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates identification of active or available substitute parts to maintain design continuity and support ongoing production requirements.

Q: Are all substitute parts available in the same packaging format?

A: All identified substitute parts utilize the 48-BSSOP surface mount package with 0.295" width and 7.50mm dimensions, providing direct mechanical compatibility. Packaging options (bulk, tube, cut tape) vary by supplier and part variant.

Q: What is the significance of Active versus Obsolete product status?

A: Active status indicates ongoing manufacturer production and supply chain availability. Obsolete status indicates discontinued production, which may result in limited inventory and higher costs. The CY74FCT162373ATPVC is the only identified substitute with Active status, making it the preferred choice for new designs and ongoing production.

Q: Can I use CY74FCT16373 variants as substitutes for the PI74FCT162373ATV?

A: CY74FCT16373 variants are electrically compatible and provide enhanced output current drive capability. However, the different base product number may indicate design variations. Substitution should be confirmed through application requirements and design verification before implementation.
