Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY74FCT16827CTPACT is determined by the following critical parameters:

• Logic function: Non-inverting buffer with 2 elements, 10 bits per element
• Output configuration: 3-state output capability
• Package compatibility: 56-TFSOP surface mount package
• Operating temperature range: -40°C ~ 85°C
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

The substitute part SN74ALVCH16827DGGR maintains functional equivalence through identical logic architecture, element count, bit configuration, and package form factor. While supply voltage ranges differ, both parts operate within overlapping temperature specifications and share identical mechanical mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVCH16827DGGR serves as the active-status equivalent for the obsolete CY74FCT16827CTPACT. Both parts maintain ROHS3 compliance and MSL 1 classification, ensuring regulatory and environmental compatibility. The substitute part is currently in active production with confirmed inventory availability (2604 pcs), providing supply chain continuity for replacement and new design applications.

Selection of the SN74ALVCH16827DGGR requires verification that system supply voltage operates within the 1.65V ~ 3.6V range. Output current specifications differ between the two parts; the substitute delivers 24mA for both high and low states compared to the original's 32mA high and 64mA low outputs. These differences must be evaluated against specific circuit load requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH16827DGGR directly replace the CY74FCT16827CTPACT in existing designs?

A: Direct replacement is possible when system supply voltage operates within 1.65V ~ 3.6V. The identical package form factor (56-TFSOP) and pin configuration enable mechanical and electrical compatibility. Output current specifications must be verified against circuit load requirements.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range (CY74FCT16827CTPACT: 4.5V ~ 5.5V versus SN74ALVCH16827DGGR: 1.65V ~ 3.6V) and output current ratings (CY74FCT16827CTPACT: 32mA/64mA versus SN74ALVCH16827DGGR: 24mA/24mA). Both maintain identical logic function, element count, bit configuration, and package specifications.

Q: Why is the CY74FCT16827CTPACT classified as obsolete?

A: Obsolete classification indicates the part is no longer in active production. The SN74ALVCH16827DGGR represents the active-status successor, offering equivalent functionality with modern manufacturing support and supply availability.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and MSL 1 classification. No compliance or certification differences exist between the two parts.

Q: What is the package compatibility between these parts?

A: Both parts use the 56-TFSOP package with 0.240" width (6.10mm). Pin configuration and mechanical dimensions are identical, enabling direct PCB footprint compatibility.
