Substitute Part Grouping Explanation

Substitution for the GTL2002D,118 is determined by the following critical parameters:

Translator Type: Voltage Level (bidirectional capability required)
Channel Configuration: 1 circuit with 2 channels per circuit
Supply Voltage Compatibility: VCCA and VCCB operating ranges must accommodate the original 1V–5.5V specification
Output Type: Open Drain or Tri-State configurations acceptable for level translation applications
Package Compatibility: Surface mount packages with equivalent or superior thermal and electrical characteristics
RoHS and Compliance Status: ROHS3 compliance and REACH unaffected status maintained

Substitute parts are grouped into two categories based on functional equivalence and package form factor:

Category 1: Direct Functional Equivalents (Active Status) Parts maintaining identical circuit topology, channel count, and bidirectional auto-direction sensing with active product status and extended temperature ranges.

Category 2: Functional Alternatives (Different Package/Performance) Parts with equivalent electrical function but different package geometries, output types (tri-state vs. open drain), or enhanced performance specifications.

Engineering Selection Recommendations

Primary Recommendation: PCA9306D,118

The PCA9306D,118 is the closest functional equivalent to the GTL2002D,118. Both devices maintain identical package geometry (8-SOIC), open-drain output configuration, and auto-direction sensing capability. The PCA9306D,118 is active status with extended operating temperature range (-40°C to 105°C versus -40°C to 85°C). Voltage compatibility is maintained within the original specification range, with VCCA supporting 1V–3.6V and VCCB supporting 1.8V–5.5V. Both parts are ROHS3 compliant with MSL 1 rating.

Secondary Recommendations: 74AVC2T45 Series (Active Status)

The 74AVC2T45GS,115 and 74AVC2T45GT,115 provide active-status alternatives with identical circuit topology and extended temperature range (-40°C to 125°C). These parts feature tri-state output instead of open-drain, suitable for applications where tri-state logic is acceptable. Supply voltage range is reduced to 0.8V–3.6V on both rails, requiring verification against system requirements. Both maintain ROHS3 compliance and MSL 1 rating.

Tertiary Recommendations: 74LVC2T45 Series (Active Status)

The 74LVC2T45DC,125 maintains the widest supply voltage range (1.2V–5.5V on both rails), closest to the original GTL2002D,118 specification. This part is active status with extended temperature range and tri-state output. Package is 8-VSSOP, requiring PCB layout modification. ROHS3 compliant with MSL 1 rating.

Obsolete Alternatives: 74AVCH2T45 Series

The 74AVCH2T45GF,115 and 74AVCH2T45GS,115 are functionally equivalent but carry obsolete status for the GF variant. The GS variant is active. These parts offer extended temperature range and tri-state output with reduced supply voltage range (0.8V–3.6V).

All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the PCA9306D,118 directly replace the GTL2002D,118 without PCB modification?

A: Yes. Both parts use identical 8-SOIC package geometry with matching pin assignments for voltage level translation applications. No PCB layout changes are required. Verify that system supply voltages fall within the PCA9306D,118 operating ranges (VCCA: 1V–3.6V, VCCB: 1.8V–5.5V).

Q: What is the functional difference between open-drain and tri-state output configurations?

A: The GTL2002D,118 uses open-drain output, which requires external pull-up resistors for high-level output. Tri-state alternatives (74AVC2T45 and 74LVC2T45 series) provide active high and low outputs without external pull-ups. Tri-state devices are suitable for applications where active drive capability is required.

Q: Are the 74AVC2T45 series parts compatible with the original 5V supply voltage specification?

A: No. The 74AVC2T45 series operates at 0.8V–3.6V on both supply rails, below the original GTL2002D,118 specification of 1V–5.5V. These parts are suitable only for 3.3V and lower supply voltage systems. For 5V applications, use the 74LVC2T45DC,125 or PCA9306D,118.

Q: Why is the 74AVCH2T45GF,115 listed as obsolete?

A: The 74AVCH2T45GF,115 carries obsolete product status from the manufacturer. While functionally equivalent, the active variant 74AVCH2T45GS,115 is recommended for new designs to ensure long-term supply availability.

Q: What is the significance of the MSL 1 rating on all substitute parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All listed parts, including the original GTL2002D,118, maintain this rating, ensuring consistent handling and storage procedures across substitutions.

Q: Can I use the 74AVC2T245GUX as a substitute for the GTL2002D,118?

A: The 74AVC2T245GUX is functionally similar but uses a different package (10-XQFN versus 8-SOIC) and has different pin assignments. PCB redesign is required. This part is suitable only if layout modification is acceptable and supply voltage requirements are met (0.8V–3.6V).
