Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The 74ALVC164245DGG-QJ (Nexperia USA Inc.) and 74AVC16T245DGG,118 (NXP USA Inc.) are the most suitable substitutes. Both maintain Active product status, ROHS3 compliance, and support the full operating temperature range of -40°C ~ 125°C. The 74ALVC164245DGG-QJ offers extended VCCB voltage range (1.5 V ~ 5.5 V) with AEC-Q100 automotive qualification, making it suitable for applications requiring broader voltage domain translation. The 74AVC16T245DGG,118 provides the widest VCCA range (0.8 V ~ 3.6 V) and maintains compatibility with the original part's temperature specifications.

Secondary Substitutes (Restricted Temperature Range):

The 74ALVC164245PAG, 74ALVC164245PAG8 (both IDT, Integrated Device Technology Inc.), and 74FCT164245TPAG (Renesas Electronics Corporation) are functionally equivalent but operate within a reduced temperature range of -40°C ~ 85°C. These parts are suitable for applications not requiring the extended low-temperature performance of the original CAVCB164245MDGGREP. The IDT variants support VCCB up to 5.5 V, enabling translation between 3.3 V and 5 V logic domains. The Renesas 74FCT164245TPAG maintains ROHS3 compliance and MSL rating of 1 (Unlimited).

Compliance Considerations:

All recommended substitutes maintain Active product status. The 74ALVC164245DGG-QJ and 74FCT164245TPAG explicitly confirm ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original part's compliance profile. Substitutes from IDT do not specify RoHS or MSL status in provided documentation.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVC164245DGG-QJ replace the CAVCB164245MDGGREP in all applications?

A: The 74ALVC164245DGG-QJ is functionally equivalent for bidirectional voltage translation with identical circuit configuration and package footprint. The primary difference is the operating temperature range: the substitute supports -40°C ~ 125°C versus the original's -55°C ~ 125°C. Applications operating above -40°C can use this substitute without modification. Applications requiring operation below -40°C must use the original CAVCB164245MDGGREP or the 74AVC16T245DGG,118.

Q: What is the difference between the IDT 74ALVC164245PAG and 74ALVC164245PAG8?

A: Both parts are electrically identical with the same voltage ranges (VCCA: 2.7 V ~ 3.6 V, VCCB: 4.5 V ~ 5.5 V) and operating temperature (-40°C ~ 85°C). The difference is packaging: 74ALVC164245PAG is supplied in Cut Tape format, while 74ALVC164245PAG8 is supplied in Bulk packaging. Selection depends on procurement and assembly requirements.

Q: Why does the 74AVC16T245DGG,118 have a different voltage specification (0.8 V ~ 3.6 V)?

A: The 74AVC16T245DGG,118 is classified as a Translation Transceiver rather than a Voltage Level Translator, though it maintains identical circuit configuration (2 elements, 8 bits per element). The wider VCCA range (0.8 V ~ 3.6 V) reflects its design for broader supply voltage compatibility. This part is suitable for applications where the original part's 1.4 V minimum VCCA is not required.

Q: Are all substitute parts available in the same 48-TSSOP package?

A: Yes. All listed substitute parts use the 48-TFSOP (0.240", 6.10mm Width) package with 48-TSSOP supplier device package designation. Package footprint and pinout are identical, enabling direct PCB-level substitution without layout modifications.

Q: Which substitute part has the broadest voltage translation capability?

A: The 74ALVC164245DGG-QJ supports VCCB from 1.5 V ~ 5.5 V, enabling translation between low-voltage (1.5 V) and standard 5 V logic domains. This makes it suitable for mixed-voltage applications. The original CAVCB164245MDGGREP is limited to 1.4 V ~ 3.6 V on both channels, restricting it to low-voltage translation scenarios.

Q: Can I use the 74ALVC164245PAG in applications requiring -55°C operation?

A: No. The 74ALVC164245PAG operates from -40°C ~ 85°C and does not support the -55°C minimum temperature of the original CAVCB164245MDGGREP. For applications requiring -55°C operation, use the original part, the 74ALVC164245DGG-QJ, or the 74AVC16T245DGG,118, which all support -40°C ~ 125°C operation.

Q: What is the significance of AEC-Q100 qualification on the 74ALVC164245DGG-QJ?

A: AEC-Q100 qualification indicates the part meets automotive-grade reliability standards. This certification is relevant for automotive and high-reliability applications. The original CAVCB164245MDGGREP does not specify automotive qualification, making the 74ALVC164245DGG-QJ preferable for automotive designs requiring equivalent functionality with enhanced qualification.
