PI74FCT16244CTAE Equivalent & Substitute Parts

Part Overview

The PI74FCT16244CTAE is a 16-bit non-inverting buffer logic IC manufactured by Diodes Incorporated in the 74FCT series. This component features 4 elements with 4 bits per element and 3-state output capability, housed in a 48-TSSOP package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the PI74FCT16244CTAE is determined by strict alignment of the following critical parameters:

Logic Type: Buffer, Non-Inverting
Number of Elements: 4
Number of Bits per Element: 4
Output Type: 3-State
Voltage Supply Range: 4.5V ~ 5.5V
Operating Temperature Range: -40°C ~ 85°C
Package Type: 48-TSSOP or 48-SSOP (mechanically compatible)
Base Product Number: 74FCT16244 or 74FCT162244 series

Substitute parts are grouped into two categories based on output current specifications and package variants. Parts with matching 32mA/64mA output current ratings provide direct electrical equivalence. Parts with reduced 24mA/24mA output current ratings are functionally compatible but with lower drive capability. Package variants (48-TSSOP vs. 48-SSOP) are mechanically interchangeable within the same footprint family.

Engineering Selection Recommendations

For direct replacement of the PI74FCT16244CTAE with matching electrical performance (32mA/64mA output current) and identical 48-TFSOP packaging, select from active-status parts: 74FCT16244ATPVG (IDT) offers the highest inventory availability at 2400 units with active product status.

For applications where reduced output current (24mA/24mA) is acceptable, 74FCT162244CTPACT (Cypress Semiconductor Corp) provides the largest inventory pool at 22,385 units with active product status and 48-TFSOP package compatibility. This part maintains full functional equivalence for logic operations while reducing power dissipation.

For 48-SSOP package variants, 74FCT162244ATPVG (IDT) and 74FCT162244ATPVG8 (Renesas) both offer active product status with 24mA/24mA output current specifications. These parts are mechanically compatible within the same footprint family.

All recommended substitutes maintain compliance with ROHS3 and REACH requirements where applicable, and operate within the specified -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a 74FCT162244 series part as a direct replacement for the PI74FCT16244CTAE?

A: Yes. The 74FCT162244 series maintains identical logic functionality, element count, bit configuration, and 3-state output characteristics. The primary difference is output current capability: 74FCT162244 parts deliver 24mA/24mA versus the original 32mA/64mA. This substitution is valid for applications where the reduced drive current does not exceed load requirements.

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

A: Both are 48-pin surface-mount packages with different body widths. 48-TFSOP measures 0.240" (6.10mm) width, while 48-BSSOP measures 0.295" (7.50mm) width. They are not directly interchangeable on the same PCB layout, but both accommodate the same die functionality and pin configuration.

Q: Why do some substitute parts show obsolete status?

A: Obsolete parts may still be available from existing inventory but are no longer manufactured. For long-term design support, prioritize active-status parts such as 74FCT162244CTPACT, 74FCT162244ATPVG, or 74FCT16244ATPVG.

Q: Are all listed substitutes ROHS3 compliant?

A: ROHS3 compliance is specified for the original PI74FCT16244CTAE and most substitute parts. Verify compliance documentation for specific part selections, particularly for parts designated as active-status from multiple manufacturers.

Q: What output current specification should I use for my design?

A: Use the output current rating of your selected substitute part. If your circuit was designed for the original 32mA/64mA specification, verify that lower-current alternatives (24mA/24mA) meet your load impedance and timing requirements before substitution.
