Substitute Part Grouping Explanation
Substitution of the PI74FCT16244CTVE is determined by the following critical parameters:
Functional Equivalence: Logic type (Buffer, Non-Inverting), number of elements (4), bits per element (4), and output type (3-State) must remain constant.
Electrical Compatibility: Supply voltage range (4.5V ~ 5.5V) and operating temperature range (-40°C ~ 85°C) must be maintained or exceeded.
Output Drive Capability: Current ratings (Output High/Low) determine load-driving capacity. The original part specifies 32mA/64mA. Substitutes with equal or greater output current are electrically compatible.
Package Compatibility: The 48-SSOP package (0.295", 7.50mm Width) is the primary package form. Substitutes in 48-TSSOP (0.240", 6.10mm Width) represent a narrower variant of the same pin count and are mechanically compatible with appropriate PCB layout adjustment.
Compliance & Status: Active product status is preferred for long-term availability. RoHS3 compliance and MSL ratings ensure environmental and moisture handling consistency.

Engineering Selection Recommendations
Primary Recommendation - Same Package, Active Status: 74FCT162244ATPVG (IDT) or 74FCT162244CTPVG (IDT) are preferred substitutes. Both maintain the 48-BSSOP package footprint, operate within identical electrical parameters, and carry active product status ensuring long-term availability. These parts are ROHS3 compliant and suitable for new designs.
Alternative - Narrower Package Variant, Highest Inventory: 74FCT162244CTPACT (Cypress Semiconductor Corp) in 48-TFSOP package offers the largest available inventory (22,385 pcs) and active status. The narrower package (0.240" vs 0.295") requires PCB layout verification but provides superior long-term supply assurance. Output current is reduced to 24mA/24mA, suitable for standard logic-level loads.
High Current Requirement - Active Status: CY74FCT16244ATPACT (Cypress Semiconductor Corp) maintains the original 32mA/64mA output current specification in a 48-TFSOP package with active product status. This part is appropriate when higher drive capability is required and package width adjustment is feasible.
Avoid - Obsolete Status: 74FCT162244ATPVCT (Texas Instruments), 74FCT16244CTPAG8 (Renesas), and 74FCT162H244CTPVC (Texas Instruments) carry obsolete status and should be selected only when existing inventory constraints or legacy design requirements mandate their use.
Frequently Asked Questions (FAQ)
Q: Can I substitute the PI74FCT16244CTVE with a part having lower output current (24mA vs 32mA)? A: Yes, if your circuit design does not require the full 32mA/64mA output drive capability. The 74FCT162244 series with 24mA/24mA output is suitable for standard logic-level loads. Verify your specific load impedance and fanout requirements before selection.
Q: What is the difference between 48-BSSOP and 48-TFSOP packages? A: Both are 48-pin surface mount packages with identical pin counts and pitch. The 48-BSSOP is 0.295" wide, while the 48-TFSOP is 0.240" wide. The narrower TFSOP variant requires PCB layout adjustment but is mechanically and electrically compatible. Consult your PCB design guidelines and component placement constraints.
Q: Why is the PI74FCT16244CTVE marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. Substitutes with active status (such as IDT or Cypress variants) are recommended for new designs to ensure long-term supply chain stability and manufacturing support.
Q: Are all listed substitutes RoHS3 compliant? A: The primary substitutes (74FCT162244ATPVG, 74FCT162244CTPVG, 74FCT162244CTPACT, CY74FCT16244ATPACT) are RoHS3 compliant. Verify compliance documentation for your specific application requirements.
Q: Which substitute offers the best inventory availability? A: 74FCT162244CTPACT (Cypress Semiconductor Corp) provides the highest inventory level at 22,385 pcs, combined with active product status and RoHS3 compliance.
Q: Can I use 74FCT162244ATPVCT as a direct replacement? A: 74FCT162244ATPVCT maintains the same 48-BSSOP package and electrical parameters but carries obsolete status. It is electrically compatible but not recommended for new designs due to discontinued production.
