Substitute Part Grouping Explanation

Substitution for the 74FCT162244CTPVG8 is determined by the following critical parameters:

Logic Type: Buffer, Non-Inverting (mandatory match)
Number of Elements: 4 (mandatory match)
Number of Bits per Element: 4 (mandatory match)
Output Type: 3-State (mandatory match)
Voltage - Supply: 4.5V ~ 5.5V (mandatory match)
Operating Temperature: -40°C ~ 85°C (mandatory match)
Current - Output High, Low: 24mA, 24mA (mandatory match for direct equivalence)

Substitute parts are grouped into two categories:

Direct Electrical Equivalents (Same Output Current): Parts maintaining 24mA output current specifications across all electrical parameters.

Functional Equivalents with Package Variations: Parts maintaining all electrical specifications but available in alternative package types (48-TSSOP vs. 48-SSOP) or from different manufacturers.

Functional Equivalents with Current Variations: Parts maintaining core logic functionality but with different output current ratings (32mA/64mA), suitable for applications with higher drive requirements.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (48-BSSOP Package):

The 74FCT162244ATPVG8 from Renesas Electronics is the primary equivalent, offering identical electrical specifications and package configuration with Active product status. This part provides the most straightforward substitution path with full compatibility.

For Active Product Status with Package Flexibility:

The 74FCT162244CTPACT and 74FCT162244ATPACT from Cypress Semiconductor are manufacturer-recommended alternatives. Both maintain identical electrical specifications but use the 48-TFSOP package (0.240" width vs. 0.295" width). These parts are currently Active and suitable for new designs or long-term supply assurance.

The CY74FCT162244TPVC from Cypress Semiconductor provides an Active alternative in the original 48-BSSOP package format, supporting direct PCB compatibility without layout modifications.

For Applications Requiring Higher Output Current:

The CY74FCT16244ATPACT from Cypress Semiconductor delivers 32mA/64mA output current capability while maintaining all other electrical parameters. This part is suitable for applications requiring enhanced drive capability and is currently Active.

Obsolete Part Considerations:

Parts designated as Obsolete (CY74FCT162244CTPVC, 74FCT162H244ATPACT, 74FCT162H244CTPVC, CY74FCT162244ATPVC, CY74FCT162244TPACT) should not be selected for new designs. These parts may be available from inventory but lack manufacturer support and long-term availability guarantees.

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT162244ATPVG8 as a direct replacement for 74FCT162244CTPVG8?

A: Yes. Both parts are manufactured by Renesas Electronics with identical electrical specifications (24mA/24mA output current, 4.5V ~ 5.5V supply, -40°C ~ 85°C operating range) and the same 48-BSSOP package. The primary difference is product status: 74FCT162244ATPVG8 is Active while 74FCT162244CTPVG8 is Last Time Buy.

Q: What is the difference between 48-BSSOP and 48-TFSOP packages?

A: Both are surface-mount packages with 48 pins. The 48-BSSOP has a 0.295" width (7.50mm), while the 48-TFSOP has a 0.240" width (6.10mm). The TFSOP is narrower and may require PCB layout modifications. Electrical functionality is identical between parts using these different packages.

Q: Are Cypress Semiconductor parts (CY74FCT162244...) compatible with the original Renesas part?

A: Yes, for electrical functionality. Cypress parts maintain identical logic specifications, output current ratings, supply voltage, and operating temperature ranges. However, some Cypress variants use the 48-TFSOP package instead of 48-BSSOP, requiring PCB layout verification.

Q: Why would I choose CY74FCT16244ATPACT over other substitutes?

A: The CY74FCT16244ATPACT provides higher output current (32mA/64mA vs. 24mA/24mA) while maintaining all other electrical parameters. Select this part only if your application requires enhanced drive capability. It is currently Active and available.

Q: Can I use obsolete parts like 74FCT162H244CTPVC?

A: Obsolete parts should not be selected for new designs. While inventory may exist, these parts lack manufacturer support, long-term availability guarantees, and updated compliance documentation. Use Active alternatives instead.

Q: What does "Last Time Buy" status mean for the original part?

A: Last Time Buy indicates the manufacturer will no longer produce this part after a specified date. Existing inventory may be available, but no new production is planned. Substitution to Active alternatives is recommended for ongoing supply security.

Q: Are all substitute parts RoHS3 compliant?

A: The main part (74FCT162244CTPVG8) and most direct equivalents are RoHS3 compliant. Verify compliance documentation for specific part numbers, particularly for obsolete variants, as compliance status may vary by manufacturer and production date.
