Substitute Part Grouping Explanation

Substitution for the 74FCT16245ATPVG8 is determined by strict equivalence across the following critical parameters:

Logic Type: Transceiver, Non-Inverting
Number of Elements: 2
Number of Bits per Element: 8
Output Type: 3-State
Voltage - Supply: 4.5V ~ 5.5V
Operating Temperature: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Base Product Number: 74FCT16245 or 74FCT162H245 series

Substitute parts are grouped into two categories based on output current specifications and package form factor. Parts with matching 32mA/64mA output current and 48-BSSOP package provide direct pin-for-pin compatibility. Parts with reduced 24mA/24mA output current or alternative package forms (48-TFSOP) require design verification for current delivery requirements.

Engineering Selection Recommendations

For direct replacement of the 74FCT16245ATPVG8 in active production, the 74FCT16245CTPVG8 from IDT provides parametric equivalence with matching 32mA/64mA output current and 48-BSSOP package form factor. This part maintains Active product status and is currently in stock.

For designs where reduced output current (24mA/24mA) is acceptable, the 74FCT162H245CTPVC from Cypress Semiconductor Corp offers an Active status alternative with the same 48-BSSOP package footprint. This part provides superior MSL rating (1 vs. 3) and unlimited moisture exposure tolerance.

Parts with 48-TFSOP package form factor (74FCT162245ATPACT, 74FCT162245CTPACT, 74FCT162H245ATPACT, 74FCT162H245CTPACT) require PCB layout modification and are not recommended for direct substitution without design review.

All substitute parts listed maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT162245ATPACT as a direct replacement for 74FCT16245ATPVG8?

A: No. While both are non-inverting transceivers with 2 elements and 8 bits per element, the 74FCT162245ATPACT uses a 48-TFSOP package (0.240" width) versus the 48-BSSOP package (0.295" width) of the original part. This requires PCB layout modification. Additionally, output current is reduced to 24mA/24mA versus the original 32mA/64mA specification.

Q: What is the difference between 74FCT16245 and 74FCT162H245 base product numbers?

A: Both are non-inverting transceivers with identical logic configuration (2 elements, 8 bits per element, 3-state output). The 74FCT162H245 variants are available from multiple manufacturers and offer improved MSL ratings (1 vs. 3). Functional compatibility is maintained across both series.

Q: Is 74FCT16245CTPVG8 from IDT a suitable replacement?

A: Yes. The 74FCT16245CTPVG8 provides parametric equivalence with matching output current (32mA/64mA), identical 48-BSSOP package, and Active product status. Packaging is Bulk rather than Tape & Reel, which may require process adjustment for automated assembly.

Q: Why do some substitutes have lower output current ratings?

A: Parts designated as 74FCT162245 or 74FCT162H245 variants from Texas Instruments and Cypress Semiconductor Corp specify 24mA/24mA output current versus the 32mA/64mA of the original 74FCT16245ATPVG8. These parts remain functionally compatible for applications where output current requirements do not exceed 24mA per output.

Q: Are all listed substitutes RoHS compliant?

A: All substitute parts listed maintain ROHS3 compliance. MSL ratings vary between 1 (Unlimited) and 3 (168 Hours), with higher MSL ratings indicating greater moisture sensitivity and requiring stricter handling during storage and assembly.
