Engineering Selection Recommendations

For Active Product Status Requirements: The 74FCT162827CTPACT (Cypress Semiconductor) and 74ACT16827DL (Texas Instruments) are recommended as primary substitutes, both maintaining active product status with full ROHS3 compliance. The 74FCT162827CTPACT provides the closest electrical equivalence with identical output current specifications and operates within the same supply voltage and temperature ranges. The 74ACT16827DL offers an alternative with active status and identical output current ratings, though it represents a different logic family within the 74ACT series.

For Package Compatibility: The 74FCT162827CTPACT uses a 56-TFSOP package (0.240", 6.10mm width), which differs from the original 56-BSSOP package. The CY74FCT16827ATPVC and CY74FCT16827CTPVC maintain the 56-BSSOP package footprint but are classified as obsolete. The 74ACT16827DL provides both active status and 56-BSSOP package compatibility.

For Output Current Specifications: Parts designated CY74FCT16827 variants feature higher output current ratings (32mA high, 64mA low) compared to the original specification (24mA, 24mA). The 74FCT162827CTPACT and 74ACT16827DL maintain the original 24mA output current specification.

For Moisture Sensitivity Considerations: The original part carries MSL 3 (168 Hours). Substitute parts with MSL 1 (Unlimited) provide superior moisture handling characteristics for extended storage and handling periods.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162827CTPACT be used as a direct replacement for the 74FCT162827CTPVG?

A: The 74FCT162827CTPACT is electrically equivalent with identical logic type, element count, bit width, output type, and supply voltage specifications. The primary difference is the package variant: 56-TFSOP versus 56-BSSOP. PCB layout modifications are required to accommodate the different package footprint.

Q: What is the significance of the output current difference in CY74FCT16827 parts?

A: The CY74FCT16827 variants specify 32mA output high and 64mA output low, compared to 24mA for both in the original part. Higher output current capability provides greater drive strength for the same logic function. This difference is acceptable in applications where the original 24mA specification is not a limiting constraint.

Q: Why is 74ACT16825DL listed as a parametric equivalent rather than a direct substitute?

A: The 74ACT16825DL differs in bit width per element: 9 bits versus 10 bits in the original part. This parametric difference requires application-level verification to confirm compatibility with system requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance, consistent with the original part specification.

Q: What packaging options are available for active product status substitutes?

A: The 74FCT162827CTPACT (Cypress Semiconductor, active status) is available in 56-TFSOP packaging. The 74ACT16827DL (Texas Instruments, active status) is available in 56-BSSOP packaging, matching the original footprint.
