Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

CY74FCT162245TPVC is the primary equivalent substitute. This part maintains identical electrical specifications (24mA output current, 4.5V to 5.5V supply voltage) and functional parameters (2 elements, 8 bits per element, 3-state output). The part is manufactured by National Semiconductor and carries Active product status with ROHS3 compliance. Inventory availability is 1,389 units.

74ACT16245DL provides an alternative direct equivalent from Texas Instruments with Last Time Buy status. This part matches all critical electrical parameters and operates within the same supply voltage and temperature ranges. Inventory availability is 3,840 units.

For Package-Compatible Substitution (48-TSSOP Alternative):

74FCT162245CTPAG and 74FCT162245CTPAG8 are functionally equivalent parts available in 48-TSSOP package format. Both are manufactured by IDT with Active product status and maintain identical electrical specifications. These parts are suitable when PCB layout accommodates the narrower 48-TSSOP footprint (0.240" width versus 0.295" for 48-BSSOP).

For Enhanced Output Current Requirements:

74FCT16245ATPAG, 74FCT16245ATPAG8, 74FCT16245ATPVG, and 74FCT16245CTPAG provide increased output current capability (32mA high, 64mA low) while maintaining the same supply voltage range and operating temperature specifications. These parts are suitable for applications requiring higher drive capability. The 74FCT16245ATPVG maintains the 48-BSSOP package format, while others use 48-TSSOP.

For Low-Voltage Applications:

SN74LVCR162245DLR is the recommended substitute for designs operating at 2.7V to 3.6V supply voltage. This Texas Instruments part maintains the 2-element, 8-bit transceiver architecture with 3-state output in 48-BSSOP package. Output current is reduced to 12mA, reflecting the lower voltage operation. Product status is Active with full ROHS3 compliance.

All recommended substitutes maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVCR162245DLR as a direct replacement for 74FCT162H245ATPVC?

A: SN74LVCR162245DLR is functionally equivalent but operates at a different supply voltage range (2.7V to 3.6V versus 4.5V to 5.5V). Direct substitution is possible only if your circuit design operates within the 2.7V to 3.6V range. The output current is also reduced to 12mA. Verify your application's voltage requirements and current demands before substitution.

Q: What is the difference between 74FCT162245 and 74FCT16245 part numbers?

A: Both are non-inverting transceiver ICs with 2 elements and 8 bits per element. The primary difference is output current capability: 74FCT162245 variants provide 24mA output current, while 74FCT16245 variants provide 32mA high and 64mA low output current. Select based on your circuit's current requirements.

Q: Are 48-BSSOP and 48-TSSOP packages interchangeable?

A: Both packages are surface-mount 48-pin configurations with identical pin assignments. The primary difference is physical size: 48-BSSOP has 0.295" width, while 48-TSSOP has 0.240" width. PCB footprints are different, so verify your layout before substituting. Pin functionality and electrical performance are identical.

Q: Why is 74FCT162H245ATPVC marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active alternatives such as CY74FCT162245TPVC, 74FCT162245CTPAG, and 74FCT162245CTPAG8 provide identical functionality and are currently in production. For new designs, select from active-status alternatives to ensure long-term supply availability.

Q: Can I substitute a part with higher output current (32mA/64mA) for one rated at 24mA?

A: Yes. Higher output current capability is a superset of lower current requirements. Parts like 74FCT16245ATPAG can replace 74FCT162H245ATPVC in applications requiring the same or lower current. Verify that your circuit design does not depend on the specific 24mA current limitation.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, mercury, cadmium, and other hazardous materials. All listed substitute parts maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory standards.

Q: Is inventory availability a factor in selecting a substitute?

A: Inventory levels indicate current stock but should not be the primary selection criterion. Prioritize based on product status (Active preferred over Last Time Buy or Obsolete), electrical compatibility, and package requirements. Inventory can fluctuate; consult your supplier for current availability.
