Key Parameters

Substitute Part Grouping Explanation

Substitution for the CY74FCT16827ATPVC is determined by the following critical parameters: logic type (non-inverting buffer), number of elements (2), bits per element, output type (3-state), supply voltage range, output current capability, package type (56-BSSOP), and operating temperature range.

The substitute parts are grouped into two categories:

Parametric Equivalent (Same Series): CY74FCT16827CTPVC maintains identical electrical specifications and series classification, differing only in temperature grade designation.

Functional Equivalents (Different Series): SN74ABT16827DL and SN74ABT16825DL provide compatible buffer functionality within the same package. SN74ABT16827DL matches the 10-bit per element configuration, while SN74ABT16825DL operates with 9 bits per element. Both support the same supply voltage range, output current ratings, and package footprint.

Voltage-Reduced Alternative: SN74ALVCH16827DLR operates at reduced supply voltage (1.65V ~ 3.6V) with lower output current (24mA, 24mA) but maintains the same logic configuration, element count, and package type.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CY74FCT16827CTPVC serves as a parametric equivalent within the same 74FCT series, maintaining all electrical and thermal characteristics of the original CY74FCT16827ATPVC.

For Active Product Status: SN74ABT16827DL is the preferred substitute, offering active product status with identical bit-per-element configuration (10 bits), matching output current ratings (32mA, 64mA), and compatible supply voltage range (4.5V ~ 5.5V). This part is available in higher inventory quantities and provides long-term procurement stability.

For Reduced Bit Configuration: SN74ABT16825DL functions as an alternative when 9-bit per element operation is acceptable within system design constraints. It maintains the same output current capability and supply voltage range as the original part.

For Low-Voltage Applications: SN74ALVCH16827DLR is suitable only when system design operates within the reduced supply voltage range of 1.65V to 3.6V. This part features lower output current capability (24mA, 24mA) and should be selected only if voltage and current requirements align with application specifications.

All substitute parts maintain ROHS3 compliance and identical package footprints (56-BSSOP), ensuring mechanical and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can SN74ABT16827DL directly replace CY74FCT16827ATPVC?

A: Yes. Both parts share identical logic configuration (2-element, 10-bit per element non-inverting buffer), output type (3-state), output current ratings (32mA, 64mA), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (56-BSSOP). The primary difference is product status: SN74ABT16827DL is active, while CY74FCT16827ATPVC is obsolete.

Q: What is the difference between SN74ABT16827DL and SN74ABT16825DL?

A: The primary difference is bit configuration per element: SN74ABT16827DL provides 10 bits per element, while SN74ABT16825DL provides 9 bits per element. All other parameters—element count (2), output type (3-state), output current (32mA, 64mA), supply voltage (4.5V ~ 5.5V), and package (56-BSSOP)—remain identical.

Q: When should SN74ALVCH16827DLR be used?

A: SN74ALVCH16827DLR is appropriate only for applications requiring reduced supply voltage operation (1.65V ~ 3.6V). This part features lower output current capability (24mA, 24mA) compared to the original specification (32mA, 64mA). Use this substitute only when both voltage and current requirements align with application design.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the 56-BSSOP package (0.295", 7.50mm width), ensuring identical PCB footprint and mechanical compatibility with the original CY74FCT16827ATPVC.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active products have ongoing manufacturing support and typically offer better long-term availability and pricing stability. Obsolete products have limited or no manufacturing support. SN74ABT16827DL and SN74ABT16825DL are active products, making them preferred for new designs and long-term procurement planning.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts, including the original CY74FCT16827ATPVC and all substitutes, are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
