Number of Circuits: 1
Channels per Circuit: 2
Voltage Range Compatibility: VCCA and VCCB support
Output Type: Open Drain or Tri-State capability
Package Type: Surface Mount compatibility
RoHS and MSL Compliance

Substitute parts are grouped into two categories:

Parametric Equivalent (Same Voltage Range): GTL2002DP/S440,118 maintains identical voltage specifications (1 V ~ 5.5 V) and electrical characteristics, differing only in packaging configuration and product status (Active vs. Obsolete).

Manufacturer Recommended Alternatives (Extended Temperature Range): Parts from the 74AVC, 74AVCH, 74LVC, and 74LVCH series provide enhanced performance with higher data rates (420 Mbps to 500 Mbps), extended operating temperature ranges (-40°C ~ 125°C), and active product status. These parts operate within narrower voltage ranges (0.8 V ~ 3.6 V or 1.2 V ~ 5.5 V) and feature Tri-State output types instead of Open Drain.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): GTL2002DP/S440,118 is the direct parametric equivalent, maintaining identical voltage specifications and operating temperature range. This part is Active status and suitable for designs requiring the same electrical characteristics as the obsolete GTL2002DP/DG,118.

Active Alternatives with Enhanced Performance: The 74LVCH2T45 series (74LVCH2T45DC-Q100H, 74LVCH2T45GN,115, 74LVCH2T45GT,115) provides voltage range compatibility (1.2 V ~ 5.5 V) closest to the original part while offering extended operating temperature (-40°C ~ 125°C), higher data rates (420 Mbps), and active product status. These parts are ROHS3 compliant and MSL Level 1.

Higher Performance Alternatives: The 74AVC and 74AVCH series deliver 500 Mbps data rates and extended temperature ranges but operate within narrower voltage ranges (0.8 V ~ 3.6 V). These are suitable for applications where the lower voltage domain is acceptable and higher speed performance is beneficial.

Fairchild Alternative: FXL2T245L10X operates within 1.1 V ~ 3.6 V range with 3-State output and -40°C ~ 85°C temperature range, matching the original operating temperature but in a different package (10-UFQFN vs. 8-TSSOP).

All recommended substitutes maintain ROHS3 compliance and MSL Level 1 specifications.

Frequently Asked Questions (FAQ)

Q: Can GTL2002DP/S440,118 be used as a direct replacement for GTL2002DP/DG,118? A: Yes. GTL2002DP/S440,118 is a parametric equivalent with identical voltage ranges (1 V ~ 5.5 V), operating temperature (-40°C ~ 85°C), and electrical characteristics. The difference is product status (Active vs. Obsolete) and packaging configuration. Both are 8-TSSOP packages.

Q: What are the key differences between the 74LVCH2T45 series and the original GTL2002DP/DG,118? A: The 74LVCH2T45 series maintains voltage compatibility (1.2 V ~ 5.5 V, overlapping with the original 1 V ~ 5.5 V range), but operates at higher data rates (420 Mbps) and extended temperature range (-40°C ~ 125°C). Output type changes from Open Drain to Tri-State. All parts are Active status with current manufacturing support.

Q: Are the 74AVC2T45 and 74AVCH2T45 series suitable replacements? A: These series are suitable only if your application operates within the 0.8 V ~ 3.6 V voltage range. They offer superior performance (500 Mbps data rate) and extended temperature range (-40°C ~ 125°C). If your design requires the full 1 V ~ 5.5 V range of the original part, the 74LVCH2T45 series is more appropriate.

Q: What is the impact of changing from Open Drain to Tri-State output? A: Open Drain output requires external pull-up resistors for high-level output. Tri-State output provides both high and low drive capability without external pull-ups. Circuit design modifications may be necessary depending on the application requirements.

Q: Does package type affect substitution compatibility? A: Package type affects PCB layout and assembly compatibility but not electrical functionality. The 8-TSSOP package of the original part is maintained in GTL2002DP/S440,118 and 74LVCH2T45DC-Q100H. Alternative packages (8-XSON, 8-VSSOP, 10-UFQFN) require PCB redesign but provide equivalent electrical performance within their specified voltage ranges.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All recommended substitute parts listed maintain ROHS3 compliance and MSL Level 1 specifications, consistent with the original GTL2002DP/DG,118.
