74FCT163244CPVG Equivalent & Substitute Parts

Part Overview

The 74FCT163244CPVG is a non-inverting buffer logic IC manufactured by Renesas Electronics Corporation, designed for 3-state output applications in 48-SSOP surface mount packaging. This part operates within a 2.7V to 3.6V supply voltage range and is currently in active product status. The 74FCT163244CPVG contains 4 elements with 4 bits per element, providing 16-bit buffering capability with controlled output drive characteristics (8mA high, 24mA low).

Substitute parts are necessary when the primary part becomes unavailable due to supply constraints, manufacturing discontinuation, or when design requirements permit operation at alternative voltage levels. Several equivalent parts from Texas Instruments and Cypress Semiconductor maintain functional compatibility while operating at 4.5V to 5.5V supply voltages.

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT163244CPVG is determined by the following critical parameters:

Functional Compatibility Requirements:

Logic type: Buffer, Non-Inverting
Number of elements: 4
Number of bits per element: 4
Output type: 3-State
Package / Case: 48-BSSOP (0.295", 7.50mm Width)
Operating temperature range: -40°C ~ 85°C (TA)

Voltage Compatibility Consideration: The 74FCT163244CPVG operates at 2.7V to 3.6V. Substitute parts operating at 4.5V to 5.5V are functionally compatible at the logic level but require circuit design verification to ensure voltage compatibility with the application's power supply and signal interface requirements.

Output Drive Capability: The 74FCT163244CPVG provides 8mA high and 24mA low output current. Substitute parts with equal or greater output current ratings (24mA/24mA or 32mA/64mA) maintain or exceed this capability.

Engineering Selection Recommendations

Primary Active Substitutes (Recommended for New Designs):

74FCT162244CTPVCT (Cypress Semiconductor) and CY74FCT162244TPVCT (Cypress Semiconductor) are active product status parts with the highest inventory availability (2200 and 2311 units respectively). Both maintain identical functional specifications to the 74FCT163244CPVG with 24mA/24mA output drive capability and 48-BSSOP packaging. These parts operate at 4.5V to 5.5V supply voltage and are ROHS3 compliant.

Secondary Active Substitute:

CY74FCT162244TPVC (Cypress Semiconductor, 1806 units in stock) provides equivalent functionality with active product status and identical electrical specifications to the primary substitutes.

Obsolete Parts (Not Recommended for New Designs):

Parts marked as obsolete (74FCT162244ATPVCT, 74FCT162H244CTPVC, CY74FCT162244ATPVC, CY74FCT162244CTPVC, CY74FCT16244ATPVC, CY74FCT16244CTPVC, CY74FCT16244TPVC) should not be selected for new designs due to discontinued product status. These parts may be considered only for legacy system maintenance or repair applications where supply is available.

Voltage Supply Consideration:

All substitute parts operate at 4.5V to 5.5V, which differs from the 74FCT163244CPVG operating range of 2.7V to 3.6V. Circuit design must accommodate this voltage difference through appropriate power supply configuration or voltage level translation if the application requires 3.3V or lower operation.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162244CTPVCT directly replace the 74FCT163244CPVG in my circuit?

A: The 74FCT162244CTPVCT maintains identical logic functionality, element count, bit configuration, output type, and 48-BSSOP packaging. However, it operates at 4.5V to 5.5V supply voltage compared to the 74FCT163244CPVG at 2.7V to 3.6V. Direct replacement is possible only if your circuit power supply and signal interface support the higher voltage range.

Q: What is the difference between the 74FCT162244 and 74FCT16244 series parts?

A: Both series maintain identical logic functionality, element count, and packaging. The primary difference is output drive capability: 74FCT162244 parts provide 24mA high/low output current, while 74FCT16244 parts provide 32mA/64mA output current. The 74FCT16244 series offers higher drive capability for applications requiring greater output current.

Q: Why are some substitute parts marked as obsolete?

A: Obsolete parts have been discontinued by their manufacturers and are no longer in active production. While inventory may remain available from distributors, these parts should not be selected for new designs. Active product status parts (74FCT162244CTPVCT, CY74FCT162244TPVC, CY74FCT162244TPVCT) are recommended for new applications.

Q: Are all substitute parts ROHS3 compliant?

A: The 74FCT163244CPVG and most substitute parts are ROHS3 compliant. Compliance information for specific parts is provided in the parameter comparison table. All listed parts are REACH unaffected.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?

A: The 74FCT163244CPVG has MSL 3 (168 hours), indicating moderate moisture sensitivity requiring controlled storage and handling. Most substitute parts have MSL 1 (unlimited), indicating lower moisture sensitivity and less stringent storage requirements. This difference may affect component handling procedures in manufacturing environments.

Q: Can I use a higher output current part (32mA/64mA) as a substitute for the 8mA/24mA original?

A: Yes. Parts with higher output current ratings (CY74FCT16244 series) provide equal or greater drive capability and are functionally compatible. The higher output current does not create compatibility issues in circuits designed for the original part's specifications.
