Engineering Selection Recommendations

Direct Equivalents (24mA Output Current):

For applications requiring exact electrical equivalence to the PI74FCT162245CTAE, select from the following parts:

74FCT162245CTPACT (Texas Instruments): Obsolete status, 873 units available
74FCT162245ATPACT (Texas Instruments): Obsolete status, 3200 units available, highest inventory among direct equivalents
74FCT162245ATPVCT (Cypress Semiconductor Corp): Active product status, 2060 units available, 48-BSSOP package
74FCT162245ATPVG (Renesas Electronics Corporation): Obsolete status, 1214 units available, 48-BSSOP package
74FCT162245CTPAG8 (IDT): Active product status, 2175 units available, 48-TFSOP package

Enhanced Performance Alternatives (32mA/64mA Output Current):

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT16245 series parts as substitutes for 74FCT162245 parts?

A: Yes, 74FCT16245 series parts are functionally compatible substitutes. The primary difference is increased output current capability (32mA/64mA versus 24mA/24mA). These parts maintain identical logic type, element count, bit configuration, supply voltage, temperature range, and 3-state output functionality. Verify that your circuit design can accommodate the higher output current specification.

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

A: Both packages are surface mount 48-pin configurations. The 48-TFSOP (Thin Fine-Pitch Small Outline Package) has a 0.240" width (6.10mm), while the 48-BSSOP (Broad Small Outline Package) has a 0.295" width (7.50mm). These are not mechanically interchangeable on the same PCB footprint. Verify your PCB design accommodates the selected package before substitution.

Q: Are obsolete parts suitable for new designs?

A: Obsolete parts carry procurement risk due to limited remaining inventory. For new designs, prioritize active product status parts such as 74FCT162245CTPAG8 (IDT), 74FCT162245ATPVCT (Cypress), or the enhanced 74FCT16245 series alternatives. Active parts provide longer-term availability and supply chain stability.

Q: What packaging options are available for the PI74FCT162245CTAE?

A: Direct equivalents are available in two package types: 48-TFSOP (0.240" width) and 48-BSSOP (0.295" width). Packaging options include Cut Tape (CT), Tape & Reel (TR), Tube, and Bulk. Verify your assembly process requirements and PCB footprint compatibility before selecting a specific package variant.

Q: Can I substitute parts with different output current ratings in my circuit?

A: Parts with higher output current ratings (32mA/64mA) are backward compatible with designs specified for 24mA/24mA output current. The higher current capability does not negatively impact circuits designed for lower current. However, verify that your circuit design does not depend on the specific current characteristics of the original part before substitution.
