CY74FCT16827CTPVC Equivalent & Substitute Parts

Part Overview

The CY74FCT16827CTPVC is a non-inverting buffer logic IC manufactured by Texas Instruments, featuring 2 elements with 10 bits per element and 3-state output capability. Housed in a 56-BSSOP surface mount package, this component operates across a 4.5V to 5.5V supply voltage range with output drive capabilities of 32mA (high) and 64mA (low). The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CY74FCT16827CTPVC is determined by the following critical parameters: logic type (non-inverting buffer), number of elements (2), bits per element, output type (3-state), package form factor (56-BSSOP), and electrical compatibility within the specified voltage and current ranges.

The substitute parts are grouped into two categories:

Manufacturer Recommended Substitute: SN74ALVCH16827DLR operates at a reduced voltage range (1.65V ~ 3.6V) with lower output current specifications (24mA, 24mA). This part maintains identical element count and bit configuration but is suitable only for applications where the lower voltage envelope is acceptable.

Parametric Equivalents: CY74FCT16827ATPVC, SN74ABT16827DL, and SN74ABT16825DL maintain the 4.5V ~ 5.5V supply voltage range and 32mA/64mA output current specifications. CY74FCT16827ATPVC is an exact parametric match within the same 74FCT series. SN74ABT16827DL provides full compatibility with identical bit-per-element configuration. SN74ABT16825DL differs only in bit-per-element count (9 bits versus 10 bits) and is suitable where the reduced bit width meets application requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the CY74FCT16827CTPVC with full parametric compatibility, SN74ABT16827DL is the primary selection. This part maintains identical electrical specifications (32mA/64mA output current, 4.5V ~ 5.5V supply voltage) and bit configuration while offering active product status, ensuring long-term availability and manufacturing support.

CY74FCT16827ATPVC serves as an alternative within the same 74FCT series for designs where series consistency is preferred, though both the original and this variant are classified as obsolete.

SN74ABT16825DL is suitable only for applications where a 9-bit-per-element configuration is functionally acceptable, as it differs from the original 10-bit specification.

SN74ALVCH16827DLR should be selected only when system architecture permits operation within the 1.65V ~ 3.6V voltage envelope and the reduced output current specifications (24mA, 24mA) are sufficient for the application load requirements.

All substitute options maintain ROHS3 compliance and identical thermal operating ranges (-40°C ~ 85°C), ensuring regulatory and environmental consistency with the original design.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16827DLR be used as a direct drop-in replacement for CY74FCT16827CTPVC?

A: No. While both parts share identical package geometry (56-BSSOP) and element/bit configuration, SN74ALVCH16827DLR operates at 1.65V ~ 3.6V supply voltage with reduced output current (24mA, 24mA). Direct substitution is only possible if the system power supply and load requirements are compatible with these reduced specifications.

Q: What is the primary difference between SN74ABT16827DL and SN74ABT16825DL?

A: Both parts are identical except for bit-per-element count. SN74ABT16827DL provides 10 bits per element, matching the original CY74FCT16827CTPVC specification. SN74ABT16825DL provides 9 bits per element and is suitable only if the application does not require the full 10-bit width.

Q: Why is CY74FCT16827ATPVC listed as a substitute if it is also obsolete?

A: CY74FCT16827ATPVC is a parametric equivalent within the same 74FCT series, offering identical electrical and thermal specifications. It is included for designs where series consistency or existing inventory of 74FCT components is a consideration, though both variants are obsolete and subject to availability constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (SN74ALVCH16827DLR, CY74FCT16827ATPVC, SN74ABT16827DL, and SN74ABT16825DL) are ROHS3 compliant, maintaining regulatory consistency with the original CY74FCT16827CTPVC.

Q: Which substitute part offers the best long-term availability?

A: SN74ABT16827DL and SN74ABT16825DL are classified as active products, providing superior long-term availability compared to the obsolete original and other substitute options. SN74ABT16827DL is recommended for new designs requiring the full 10-bit-per-element specification.
