CALVC164245IDGGREP Equivalent & Substitute Parts

Part Overview

The CALVC164245IDGGREP is a voltage level translator IC manufactured by Texas Instruments, classified as a bidirectional logic translator in the 74ALVC series. This device translates signals between two different voltage domains, featuring 2 circuits with 8 channels per circuit in a 48-TSSOP surface mount package. The part is currently active in production with 1693 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives from different manufacturers or product lines within the same series.

Substitute Part Grouping Explanation

Substitution eligibility for the CALVC164245IDGGREP is determined by the following critical parameters:

Translator type (Voltage Level)

Output type (Tri-State, Non-Inverted)
Package type (48-TSSOP)
Voltage operating ranges (VCCA and VCCB)
Operating temperature range
Surface mount compatibility

Substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalents maintain identical electrical specifications and voltage ranges, differing only in packaging format (Cut Tape vs. Tape & Reel) or product status. These include SN74ALVC164245DGGR, SN74ALVC164245DGGT, and 74ALVC164245DGGRE4.

Upgrade Parts offer extended specifications while maintaining core functionality. The 74ALVC164245DGG-QJ from Nexperia expands voltage ranges (VCCA: 1.5 V ~ 3.6 V, VCCB: 1.5 V ~ 5.5 V) and operating temperature (-40°C ~ 125°C), with automotive qualification (AEC-Q100).

Manufacturer Recommended Alternatives from IDT (74ALVC164245PAG and 74ALVC164245PAG8) provide functional equivalence with slightly different voltage specifications (VCCA: 2.7 V ~ 3.6 V, VCCB: 4.5 V ~ 5.5 V) and alternative packaging formats.

Engineering Selection Recommendations

For direct replacement with identical specifications: Select SN74ALVC164245DGGR or SN74ALVC164245DGGT. Both are Texas Instruments products with active product status, identical voltage ranges, and equivalent electrical performance. SN74ALVC164245DGGR offers significantly higher inventory availability (29989 units).

For extended operating temperature range: The 74ALVC164245DGG-QJ from Nexperia provides automotive-grade qualification (AEC-Q100) with expanded operating temperature range (-40°C ~ 125°C) and lower minimum voltage thresholds (VCCA: 1.5 V, VCCB: 1.5 V). This part is suitable for applications requiring enhanced thermal performance or automotive compliance.

For alternative packaging formats: The 74ALVC164245PAG and 74ALVC164245PAG8 from IDT provide functional equivalence with different packaging options. Note that these parts have narrower voltage specifications (VCCA minimum 2.7 V, VCCB minimum 4.5 V) and should be selected only when the application voltage ranges are compatible.

Avoid 74ALVC164245DGGRE4 for new designs, as this part is discontinued at DiGi Electronics despite current inventory availability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical package dimensions (48-TFSOP, 0.240", 6.10mm Width).

Frequently Asked Questions (FAQ)

Q: Can I use SN74ALVC164245DGGR as a direct replacement for CALVC164245IDGGREP?

A: Yes. Both parts are Texas Instruments products with identical electrical specifications, voltage ranges, operating temperature, and package type. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Electrical performance and pinout are equivalent.

Q: What is the difference between the Texas Instruments and Nexperia versions?

A: The Nexperia 74ALVC164245DGG-QJ offers extended specifications: lower minimum voltage thresholds (VCCA: 1.5 V vs. 2.3 V, VCCB: 1.5 V vs. 3 V) and higher maximum operating temperature (125°C vs. 85°C). It includes automotive qualification (AEC-Q100). Select this part only if your application requires these enhanced specifications.

Q: Why do the IDT parts (74ALVC164245PAG and 74ALVC164245PAG8) have different voltage ranges?

A: IDT's implementation specifies narrower voltage operating ranges (VCCA: 2.7 V ~ 3.6 V, VCCB: 4.5 V ~ 5.5 V) compared to the Texas Instruments baseline. These parts are functionally equivalent but require verification that your application voltage levels fall within these narrower specifications before substitution.

Q: Is the 48-TSSOP package compatible across all substitute parts?

A: Yes. All listed substitute parts use the 48-TFSOP (0.240", 6.10mm Width) package with 48-TSSOP supplier device package designation. Physical dimensions and pinout are identical, allowing direct PCB compatibility.

Q: What does "Discontinued at DiGi Electronics" mean for the 74ALVC164245DGGRE4?

A: This part is no longer actively distributed through DiGi Electronics but may have remaining inventory from other sources. For new designs and long-term supply assurance, select active products such as SN74ALVC164245DGGR or SN74ALVC164245DGGT.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.
