74FCT164245TPVG Equivalent & Substitute Parts
Part Overview
The 74FCT164245TPVG is a voltage level translator IC manufactured by Renesas Electronics Corporation, designed for bidirectional signal translation between different voltage domains. This device features 2 circuits with 8 channels per circuit in a 48-SSOP package, translating signals between VCCA (2.7V–3.6V) and VCCB (4.5V–5.5V) supply voltages. The part is active in production status with ROHS3 compliance and is suitable for applications requiring reliable voltage level conversion in surface-mount configurations.
Equivalent and substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing flexibility, or when design optimization calls for different electrical characteristics within compatible parameter ranges.

Substitute Part Grouping Explanation
Substitution of the 74FCT164245TPVG is determined by the following critical parameters:
- Bidirectional 2-circuit, 8-channel architecture: All substitute parts maintain this core topology
- Voltage translation capability: Substitute parts must support translation between low-voltage (1.65V–3.6V) and high-voltage (3V–5.5V) domains, encompassing the original part's VCCA and VCCB ranges
- Tri-state output configuration: All substitutes provide tri-state, non-inverted outputs for bus-compatible operation
- Surface-mount packaging: All substitutes use surface-mount technology; package variants (48-SSOP, 48-TSSOP, 48-TFSOP, 48-TVSOP) are mechanically and electrically interchangeable within PCB design constraints
- Operating temperature range: Substitutes operate within -40°C to 85°C or -40°C to 125°C, covering the original specification
- Compliance standards: All substitutes maintain ROHS3 compliance and EAR99 export classification
Substitute parts are grouped by manufacturer series (74LVC, 74LVCH, 74ALVC, 74AVC) and packaging format. Each series represents a different logic family with compatible electrical characteristics for this application class.

Engineering Selection Recommendations
Direct Substitutes (48-BSSOP Package, Identical Footprint)
SN74LVC16T245DL, SN74LVC16T245DLR, and SN74LVCH16T245DLR from Texas Instruments are direct pin-compatible replacements in the 48-BSSOP package. These parts support the full voltage translation range required by the 74FCT164245TPVG and maintain tri-state output functionality. All three are active products with ROHS3 compliance. The primary difference is packaging format (tube vs. cut tape vs. tape & reel), which affects procurement and assembly processes but not electrical performance.
SN74ALVC164245DL and CALVC164245IDLREP provide voltage level translation with slightly narrower VCCA ranges (2.3V–3.6V minimum) compared to the original part (2.7V–3.6V), but remain compatible for most applications. Both are active products with MSL 1 rating, indicating superior moisture resistance compared to the original MSL 3 specification.
Alternative Package Formats (48-TSSOP, 48-TFSOP)
74ALVC164245DGG-QJ (Nexperia) and 74AVC16T245DGG,118 (NXP) use 48-TSSOP packaging with reduced footprint dimensions. These parts require PCB layout modification but offer extended operating temperature range (-40°C to 125°C) and improved MSL ratings. The 74ALVC164245DGG-QJ carries AEC-Q100 automotive qualification, suitable for automotive-grade applications.
CLVC16T245MDGGEP and CLVC16T245MDGGREP (Texas Instruments) use 48-TFSOP packaging with the narrowest footprint (0.240" width). These maintain the 74LVC series characteristics with full voltage translation capability and MSL 1 rating.
SN74AVC16T245DGVR (Texas Instruments) uses 48-TFSOP packaging with the most compact footprint (0.173" width, 48-TVSOP). This part supports the widest voltage range (1.2V–3.6V) and is suitable for ultra-low-voltage applications.
All substitute parts are active products with ROHS3 compliance and EAR99 export classification, matching the regulatory status of the original part.
Frequently Asked Questions (FAQ)
Q: Can I use SN74LVC16T245DL as a direct replacement for 74FCT164245TPVG?
A: Yes. Both parts maintain 2 circuits with 8 channels per circuit, tri-state output configuration, and 48-BSSOP package footprint. The SN74LVC16T245DL supports voltage translation across the required range (1.65V–5.5V supply), encompassing the original part's VCCA (2.7V–3.6V) and VCCB (4.5V–5.5V) specifications. No PCB layout changes are required.
Q: What is the difference between 48-BSSOP, 48-TSSOP, and 48-TFSOP packages?
A: These are all surface-mount packages with 48 pins but different physical dimensions. 48-BSSOP (0.295" width) is the original package. 48-TSSOP (0.240" width) and 48-TFSOP (0.240" width) offer reduced footprint for space-constrained designs. 48-TVSOP (0.173" width) provides the most compact option. Pin pitch and electrical characteristics remain compatible; PCB layout must accommodate the specific package dimensions.
Q: Why does the 74FCT164245TPVG have MSL 3 while most substitutes have MSL 1?
A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to ambient conditions (typically 30°C/85% RH) before soldering. MSL 3 allows 168 hours; MSL 1 allows unlimited storage. Substitutes with MSL 1 offer superior moisture resistance and longer shelf life, reducing risk of moisture-induced failures during assembly.
Q: Can I substitute a part with a different operating temperature range?
A: Yes, if your application operates within the overlapping temperature range. The original part operates -40°C to 85°C. Substitutes with -40°C to 125°C range (74ALVC164245DGG-QJ, 74AVC16T245DGG,118) provide extended high-temperature capability. Verify your actual operating conditions fall within the substitute's specification.
Q: What is the difference between 74LVC, 74LVCH, 74ALVC, and 74AVC series?
A: These represent different logic families with varying voltage ranges and performance characteristics. 74LVC supports 1.65V–5.5V supply. 74LVCH is a variant of 74LVC. 74ALVC supports lower VCCA minimums (1.5V–2.3V depending on part) with improved voltage translation flexibility. 74AVC supports the widest voltage range (0.8V–3.6V) for ultra-low-voltage applications. All maintain compatible pin configurations and tri-state output functionality for this application class.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original 74FCT164245TPVG specification. All are also classified as EAR99 for export purposes.
Q: Which substitute offers the best availability?
A: According to inventory data, 74AVC16T245DGG,118 (NXP) has the highest stock level at 36,888 pieces. SN74ALVC164245DL (Texas Instruments) has 40,928 pieces available. Both represent high-volume alternatives suitable for immediate procurement.
