74ACT16240DL Equivalent & Substitute Parts

Part Overview

The 74ACT16240DL is a Buffer, Inverting logic IC featuring 4 elements with 4 bits per element and 3-state output capability. Manufactured by Texas Instruments in a 48-SSOP surface mount package, this component operates across a 4.5V to 5.5V supply voltage range with output currents of 24mA for both high and low states. The part is classified as Last Time Buy, indicating limited future availability. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain flexibility for applications requiring this specific logic function.

Substitute Part Grouping Explanation

Substitute parts for the 74ACT16240DL are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Logic function: Buffer, Inverting with identical element and bit configuration
Output characteristics: 3-state output with matching 24mA drive capability
Electrical specifications: 4.5V to 5.5V supply voltage range and -40°C to 85°C operating temperature
Physical compatibility: 48-BSSOP package with identical pin configuration and 0.295" width
Compliance standards: ROHS3 compliance and MSL Level 1 rating

Two substitute parts meet these criteria: the 74ACT16240DLR (manufacturer recommended, active status) and the CY74FCT162240CTPVC (parametric equivalent, obsolete status).

Engineering Selection Recommendations

The 74ACT16240DLR is the primary substitute for the 74ACT16240DL. Both parts are manufactured by Texas Instruments within the 74ACT series and share identical electrical and mechanical specifications. The 74ACT16240DLR maintains Active product status, ensuring continued availability and long-term supply chain stability. The only difference is packaging format: the original uses Tube packaging while the substitute uses Tape & Reel (TR) format, which is standard for high-volume production environments.

The CY74FCT162240CTPVC represents a parametric equivalent from the 74FCT series. While all electrical and mechanical parameters match the original part, this component carries Obsolete product status. Selection of this part should be limited to applications where existing inventory exists and no alternative is available, as future procurement will not be possible.

For new designs and ongoing production, the 74ACT16240DLR is the recommended choice due to its Active status and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16240DLR be used as a direct replacement for the 74ACT16240DL?

A: Yes. Both parts are electrically and mechanically identical, with matching logic function, output drive capability, supply voltage range, operating temperature, and 48-BSSOP package configuration. The difference in packaging format (Tube versus Tape & Reel) does not affect functional compatibility.

Q: What is the difference between the 74ACT and 74FCT series?

A: The 74ACT16240DL and 74ACT16240DLR belong to the 74ACT series, while the CY74FCT162240CTPVC belongs to the 74FCT series. Despite the series designation difference, the CY74FCT162240CTPVC meets all specified electrical and mechanical parameters for substitution. However, the 74FCT part is classified as Obsolete.

Q: Why is the CY74FCT162240CTPVC listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and will not accept new orders. While existing inventory may be available, this part should not be selected for new designs or long-term production commitments.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: What packaging formats are available?

A: The 74ACT16240DL is supplied in Tube packaging. The 74ACT16240DLR is supplied in Tape & Reel (TR) format, which is preferred for automated assembly and high-volume production. The CY74FCT162240CTPVC is supplied in Tube packaging.
