Engineering Selection Recommendations
For Direct Replacement (Identical Electrical Characteristics):
The 74ACT16244DLR, 74FCT162244ATPVG, and 74FCT162244CTPVG are direct substitutes with matching supply voltage (4.5V ~ 5.5V), output current (24mA, 24mA), and operating temperature range (-40°C ~ 85°C). All three are active products with ROHS3 compliance, ensuring long-term availability and regulatory compliance. The 74ACT16244DLR is manufactured by Texas Instruments, maintaining original manufacturer continuity.
For Enhanced Current Drive Applications:
The 74FCT16244ATPVG and 74FCT16244CTPAG8 provide increased output current capability (32mA, 64mA) while maintaining identical supply voltage and temperature specifications. These parts are suitable for applications requiring higher drive strength. The 74FCT16244ATPVG is active status, while 74FCT16244CTPAG8 is obsolete.
For Lower Voltage Operation:
The SN74LVC162244ADLR operates at reduced supply voltage (1.65V ~ 3.6V) with lower output current (12mA, 12mA) and extended temperature range (-40°C ~ 125°C). This part is suitable for low-power applications and is active status with ROHS3 compliance.
For Reduced Voltage with Lower Current:
The 74FCT163244APVG and 74FCT163244APVG8 operate at 2.7V ~ 3.6V supply voltage with asymmetric output current (8mA, 24mA). Both are active products suitable for mixed-voltage systems.
Compliance and Availability:
All recommended active substitutes maintain ROHS3 compliance and MSL ratings compatible with standard manufacturing processes. The 74FCT162244CTPVCT (Cypress Semiconductor) is the only active product with identical electrical specifications to the original part.
Frequently Asked Questions (FAQ)
Q: Can the SN74LVC162244ADLR replace the CY74FCT162244TPVCT in a 5V system?
A: No. The SN74LVC162244ADLR operates at maximum 3.6V supply voltage and cannot be used in systems requiring 5.5V operation. It is suitable only for 3.3V or lower voltage designs.
Q: What is the difference between 74FCT162244 and 74FCT16244 part numbers?
A: The 74FCT16244 variants provide higher output current capability (32mA, 64mA) compared to 74FCT162244 (24mA, 24mA). Both maintain identical logic function and package configuration.
Q: Are all substitute parts available in the same 48-BSSOP package?
A: Most substitutes use 48-BSSOP packaging. The 74FCT16244CTPAG8 uses 48-TSSOP (0.240", 6.10mm Width), which has different physical dimensions and is not pin-compatible without PCB redesign.
Q: Which substitute offers the best long-term availability?
A: The 74ACT16244DLR, 74FCT162244ATPVG, and 74FCT162244CTPVG are all active products with confirmed inventory. The 74ACT16244DLR maintains Texas Instruments manufacturing, ensuring consistent supply chain support.
Q: Can I use a substitute with higher output current in place of the original part?
A: Yes. The 74FCT16244ATPVG and 74FCT16244CTPAG8 with 32mA/64mA output current are backward compatible with applications designed for 24mA/24mA output. Higher current capability does not degrade performance in lower-current applications.
Q: What is the impact of MSL (Moisture Sensitivity Level) differences?
A: MSL 1 (Unlimited) parts like the original CY74FCT162244TPVCT have no moisture sensitivity restrictions. MSL 3 parts like 74FCT163244APVG8 require controlled storage conditions (168 hours maximum exposure at specified humidity). Standard manufacturing processes accommodate both levels.
Q: Are all substitutes ROHS3 compliant?
A: Most active substitutes are ROHS3 compliant. Verify specific part documentation for compliance certification, particularly for parts from different manufacturers or with obsolete status.
