74FCT163244APVG Equivalent & Substitute Parts

Part Overview

The 74FCT163244APVG 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 device operates across a 2.7V to 3.6V supply voltage range and is classified as Active product status. The 74FCT163244APVG contains 4 elements with 4 bits per element, providing 16-bit buffering capability with independent 3-state control.

Substitute parts are necessary when the primary part becomes unavailable, when alternative voltage specifications are required for system compatibility, or when different packaging formats better suit manufacturing requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT163244APVG 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: -40°C ~ 85°C (TA)

Voltage Specification Consideration: The 74FCT163244APVG operates at 2.7V ~ 3.6V. Substitute parts operating at 4.5V ~ 5.5V are functionally compatible in systems where the higher voltage specification does not conflict with circuit design requirements. Both voltage ranges maintain the same logic family (74FCT) and functional architecture.

Current Output Specification: The 74FCT163244APVG provides 8mA high and 24mA low output current. Substitute parts with higher output current ratings (24mA/24mA or 32mA/64mA) are compatible as they exceed minimum drive requirements.

Product Status: Active and Obsolete parts are both listed as substitutes. Obsolete parts may have limited availability but maintain full functional and electrical compatibility.

Engineering Selection Recommendations

For Active Product Status Priority: Select CY74FCT162244TPVCT, CY74FCT162244TPVC, or 74FCT162244CTPVCT. These parts maintain Active product status with full manufacturer support and long-term availability. All three are ROHS3 compliant and operate at 4.5V ~ 5.5V with 24mA output current specifications.

For Low-Voltage Applications (2.7V ~ 3.6V): The 74FCT163244APVG remains the only substitute within the specified 2.7V ~ 3.6V voltage range. No alternative parts operate at this voltage specification.

For Higher Output Current Requirements: CY74FCT16244ATPVC, CY74FCT16244CTPVC, and CY74FCT16244TPVC provide 32mA high and 64mA low output current, exceeding the 74FCT163244APVG specifications. These parts are suitable for applications requiring enhanced drive capability.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and EAR99 export classification. Moisture Sensitivity Level varies between MSL 1 (Unlimited) for most substitutes and MSL 3 (168 Hours) for the primary part.

Frequently Asked Questions (FAQ)

Q: Can I use a 4.5V ~ 5.5V substitute part in a 2.7V ~ 3.6V circuit? A: No. The 74FCT163244APVG operates at 2.7V ~ 3.6V. Substitute parts rated for 4.5V ~ 5.5V require higher supply voltage and are not compatible with 2.7V ~ 3.6V circuits without circuit redesign.

Q: Are Obsolete parts suitable for new designs? A: Obsolete parts are functionally equivalent but have limited availability and no manufacturer support. For new designs, select Active status parts: CY74FCT162244TPVCT, CY74FCT162244TPVC, or 74FCT162244CTPVCT.

Q: What is the difference between 74FCT162244 and 74FCT16244 base part numbers? A: The 74FCT16244 series provides higher output current (32mA/64mA) compared to 74FCT162244 (24mA/24mA). Both maintain identical logic architecture and 48-BSSOP packaging.

Q: Do all substitute parts use the same 48-BSSOP package? A: Yes. All listed substitute parts use 48-BSSOP (0.295", 7.50mm Width) surface mount packaging, ensuring mechanical compatibility with the 74FCT163244APVG.

Q: What is the significance of Moisture Sensitivity Level (MSL)? A: MSL 3 (168 Hours) for the 74FCT163244APVG requires storage in controlled humidity conditions. Most substitutes feature MSL 1 (Unlimited), allowing indefinite storage without moisture control.

Q: Are there packaging format differences among substitutes? A: Substitute parts are available in Bulk, Cut Tape (CT) & Digi-Reel®, and Tube packaging formats. All maintain the same 48-SSOP supplier device package and are functionally interchangeable.
