Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT162240CTPVC are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Logic Type: Buffer, Inverting (4 elements, 4 bits per element)
• Output Type: 3-State
• Output Current: 24mA (both high and low states)
• Package: 48-BSSOP surface mount
• Operating Temperature Range: -40°C ~ 85°C (TA)
• RoHS3 Compliance and MSL Level 1

Substitute parts are grouped into two categories:

MFR Recommended Substitute: SN74ALVCH16240DLR operates at a lower voltage range (1.65V ~ 3.6V) while maintaining identical logic configuration, element count, bit count, output type, and current specifications. This part is suitable for applications where lower supply voltage operation is acceptable.

Parametric Equivalent: 74ACT16240DL maintains the same supply voltage range (4.5V ~ 5.5V) as the original part, providing direct voltage compatibility while preserving all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Voltage Compatibility (4.5V ~ 5.5V Supply): The 74ACT16240DL is the parametric equivalent, maintaining identical supply voltage specifications as the CY74FCT162240CTPVC. This part carries Last Time Buy status, indicating extended availability compared to the obsolete original part. Both parts are ROHS3 compliant with MSL Level 1 rating.

For Lower Voltage Applications (1.65V ~ 3.6V Supply): The SN74ALVCH16240DLR is the manufacturer-recommended substitute when system voltage requirements permit operation at lower supply levels. This part maintains all functional and mechanical specifications while extending voltage flexibility. Both parts are ROHS3 compliant with MSL Level 1 rating.

Availability Consideration: The 74ACT16240DL offers superior long-term availability due to its Last Time Buy status, making it the preferred choice for new designs or production planning when voltage compatibility permits.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH16240DLR be used as a direct replacement in a 5V system? A: No. The SN74ALVCH16240DLR operates at 1.65V ~ 3.6V supply voltage and is not rated for 5V operation. Use only in systems designed for 3.6V maximum supply voltage.

Q: Are all substitute parts pin-compatible with the original CY74FCT162240CTPVC? A: Yes. All substitute parts use the 48-BSSOP package with identical pinout and mechanical dimensions (0.295", 7.50mm width), enabling direct PCB replacement.

Q: What is the difference between the 74FCT and 74ACT series? A: Both series operate at 4.5V ~ 5.5V supply voltage with identical logic configuration, element count, and output specifications. The primary difference is product status: CY74FCT162240CTPVC is obsolete, while 74ACT16240DL is Last Time Buy, offering extended procurement availability.

Q: Do all parts meet the same environmental and compliance standards? A: Yes. All three parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and operate across the -40°C ~ 85°C temperature range.

Q: Which substitute should be selected for new design implementation? A: For new designs requiring 4.5V ~ 5.5V operation, select 74ACT16240DL due to its Last Time Buy status and extended availability. For systems operating at 3.6V or lower, select SN74ALVCH16240DLR.
