Substitute Part Grouping Explanation

Substitute parts for the CALVC164245IGQLREP are identified based on strict equivalence of core functional parameters: translator type (voltage level), channel configuration (bidirectional, 2 circuits, 8 channels per circuit), output type (tri-state, non-inverted), and operating temperature range (-40°C to 85°C).

The substitute parts 74FCT164245TPAG and 74FCT164245TPAG8 maintain functional equivalence through identical circuit topology and channel architecture. Both substitutes are manufactured by Renesas Electronics Corporation and belong to the 74FCT series, which provides compatible voltage translation functionality.

Key parameters determining substitution validity:

• Bidirectional channel configuration with 2 circuits and 8 channels per circuit
• Tri-state, non-inverted output type
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and MSL 1 rating
• Surface mount technology

The primary distinction between the main part and substitutes is the package format (56-VFBGA versus 48-TSSOP) and voltage specifications, which require design-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The 74FCT164245TPAG and 74FCT164245TPAG8 are functionally equivalent substitutes for the discontinued CALVC164245IGQLREP based on matching circuit topology, channel configuration, and output characteristics. Both substitute parts maintain active product status with Renesas Electronics Corporation, ensuring long-term availability and supply chain stability.

The primary consideration for component selection is the package format transition from 56-VFBGA to 48-TSSOP, which requires PCB layout redesign and may impact thermal management characteristics. The voltage specification differences (VCCA minimum of 2.7 V versus 2.3 V, and VCCB minimum of 4.5 V versus 3 V) must be evaluated against specific application requirements to confirm compatibility.

Both substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The 74FCT164245TPAG8 variant offers higher inventory availability in cut tape and Digi-Reel packaging formats, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Are the 74FCT164245TPAG and 74FCT164245TPAG8 truly equivalent to the CALVC164245IGQLREP?

A: Both parts provide functional equivalence in voltage level translation with identical circuit topology (2 circuits, 8 channels per circuit), bidirectional operation, and tri-state non-inverted output. The primary differences are package format (48-TSSOP versus 56-VFBGA) and voltage operating ranges, which require application-specific validation.

Q: What is the difference between 74FCT164245TPAG and 74FCT164245TPAG8?

A: Both parts are electrically identical. The difference lies in packaging format: 74FCT164245TPAG is supplied in tube packaging, while 74FCT164245TPAG8 is supplied in cut tape and Digi-Reel formats. Selection depends on procurement volume and handling requirements.

Q: Can I use these substitutes without PCB redesign?

A: No. The package format change from 56-VFBGA to 48-TSSOP requires PCB layout modification, including footprint redesign and potential signal routing adjustments. Thermal management characteristics may also differ between packages.

Q: Are the voltage specifications compatible with my application?

A: The substitute parts specify VCCA minimum of 2.7 V (versus 2.3 V for the original) and VCCB minimum of 4.5 V (versus 3 V for the original). Applications operating at the lower voltage boundaries of the original part may require circuit redesign or alternative component selection.

Q: What is the inventory status of these substitutes?

A: The 74FCT164245TPAG maintains 1219 pieces in stock (tube packaging), while the 74FCT164245TPAG8 maintains 29200 pieces in stock (cut tape and Digi-Reel). Both parts are active products with established supply chains.
