Output type: 3-State
Supply voltage range: 4.5V ~ 5.5V
Output drive current: 32mA (high) / 64mA (low)

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Replacement):

The following parts maintain identical electrical specifications (4.5V ~ 5.5V supply, 32mA/64mA output current) and mechanical compatibility (48-TFSOP package):

74ABT16245ADGGR (Texas Instruments, Active status) — Preferred choice for new designs due to active product status and full parametric equivalence
SN74ABT16245ADGGR (Texas Instruments, Active status) — Functionally identical to 74ABT16245ADGGR with active support
SN74ABTH16245DGGR (Texas Instruments, Active status) — Active alternative with identical electrical and mechanical specifications
74FCT16245CTPAG (Renesas Electronics, Active status) — Direct parametric equivalent with active product status

Functional Alternatives (Requires Design Verification):

SN74LVCR16245ADGGR (Texas Instruments, Active status) — Operates at reduced supply voltage (1.65V ~ 3.6V) with lower output current (12mA/12mA). Suitable only if system voltage and current requirements permit lower operating parameters.

Parts with Reduced Output Current (Requires Design Verification):

74FCT162245ATPAG (Renesas Electronics, Obsolete) — Reduced output current (24mA/24mA) compared to original specification
74FCT162245CTPAG (IDT, Active status) — Reduced output current (24mA/24mA); verify load requirements before selection

Not Recommended:

74FCT162245ATPVG (Renesas Electronics, Obsolete) — Different package type (48-BSSOP vs. 48-TFSOP) and higher MSL rating (3 vs. 1); mechanical incompatibility with original footprint

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVCR16245ADGGR as a direct replacement for CY74FCT16245CTPACT?

A: No. While both are non-inverting transceivers in 48-TFSOP packages, the SN74LVCR16245ADGGR operates at a different supply voltage range (1.65V ~ 3.6V vs. 4.5V ~ 5.5V) and provides significantly lower output current (12mA/12mA vs. 32mA/64mA). Use only if your system design accommodates these reduced electrical specifications.

Q: What is the difference between 74ABT16245ADGGR and SN74ABT16245ADGGR?

A: Both parts are functionally and electrically identical. The difference is in the manufacturer's part numbering convention. Both are Texas Instruments products with active status, identical supply voltage (4.5V ~ 5.5V), output current (32mA/64mA), and 48-TFSOP packaging. Either can be used interchangeably.

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts are included for reference and compatibility verification in existing designs. For new designs, prioritize active-status alternatives such as 74ABT16245ADGGR, SN74ABT16245ADGGR, SN74ABTH16245DGGR, or 74FCT16245CTPAG to ensure long-term supply availability and manufacturer support.

Q: Can I use 74FCT162245CTPAG if my design requires 32mA/64mA output current?

A: No. The 74FCT162245CTPAG provides only 24mA/24mA output current, which is insufficient for applications requiring the original 32mA/64mA specification. Verify your circuit's load requirements before substitution.

Q: Is the 48-BSSOP package compatible with the original 48-TFSOP footprint?

A: No. The 48-BSSOP package (0.295" width, 7.50mm) differs from the 48-TFSOP package (0.240" width, 6.10mm). PCB layout and footprint modifications are required. The 74FCT162245ATPVG is not recommended for direct board-level replacement without redesign.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, consistent with the original CY74FCT16245CTPACT specification.
