GTL2012DC,125 Equivalent & Substitute Parts

Part Overview

The GTL2012DC,125 is a mixed signal translator IC manufactured by NXP USA Inc., designed for bidirectional signal translation between LVTTL and GTL logic levels. This 8-VSSOP surface mount device features 1 circuit with 2 channels per circuit and non-inverted output configuration. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the GTL2012DC,125 is determined by the following critical parameters:

• Translator Type: Mixed Signal
• Channel Type: Bidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Input Signal: LVTTL
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts must maintain these core electrical and functional characteristics. Package variations are acceptable provided the mounting type remains surface mount and the device footprint is compatible with the application's PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

GTL2012DP,118 (NXP USA Inc.) is the primary substitute for the GTL2012DC,125. Both devices share identical electrical specifications, translator type, channel configuration, and operating temperature range. The GTL2012DP,118 is currently in active production status and maintains ROHS3 compliance and MSL 1 rating. The primary difference is the package format: 8-TSSOP versus 8-VFSOP. This substitute is recommended when PCB layout can accommodate the slightly larger 8-TSSOP footprint (0.118" versus 0.091" width).

SN74GTLP1394D, SN74GTLP1394PW, and SN74GTLP1394PWR (Texas Instruments) are alternative substitutes that maintain core bidirectional mixed signal translator functionality with LVTTL input and identical operating temperature specifications. These devices are active production parts with ROHS3 compliance. The key distinction is the output signal specification (GTLP versus GTL) and output type configuration (Tri-State, Inverted versus Non-Inverted). These substitutes are suitable when the application circuit design accommodates GTLP output levels and inverted output logic. Package options include 16-SOIC and 16-TSSOP formats, requiring PCB layout verification.

All substitute parts maintain the required compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity level specifications of the original part.

Frequently Asked Questions (FAQ)

Q: Can GTL2012DP,118 be used as a direct replacement for GTL2012DC,125?

A: GTL2012DP,118 is electrically equivalent and functionally compatible. The primary consideration is package footprint compatibility. GTL2012DP,118 uses 8-TSSOP packaging (0.118" width) compared to the original 8-VFSOP (0.091" width). PCB layout verification is required to confirm the larger package can be accommodated in the available space.

Q: What is the difference between GTL and GTLP output signals?

A: GTL and GTLP are distinct logic level standards. The GTL2012DC,125 and GTL2012DP,118 output GTL levels, while the SN74GTLP1394 series outputs GTLP levels. These are not interchangeable without circuit design verification. GTLP devices also feature tri-state, inverted output configuration versus the non-inverted output of the GTL2012 series.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (GTL2012DP,118, SN74GTLP1394D, SN74GTLP1394PW, SN74GTLP1394PWR) are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity level rating, matching the original GTL2012DC,125 specifications.

Q: What packaging options are available for substitutes?

A: GTL2012DP,118 is available in 8-TSSOP (0.118", 3.00mm width). SN74GTLP1394D is available in 16-SOIC (0.154", 3.90mm width). SN74GTLP1394PW and SN74GTLP1394PWR are available in 16-TSSOP (0.173", 4.40mm width). Package selection depends on PCB layout constraints and application requirements.

Q: Why is the GTL2012DC,125 classified as obsolete?

A: The GTL2012DC,125 is no longer in active production. The GTL2012DP,118 represents the active production equivalent from NXP USA Inc. with identical electrical specifications and improved availability.

Q: Can I use SN74GTLP1394 series devices if my circuit requires non-inverted output?

A: SN74GTLP1394 series devices feature tri-state, inverted output configuration. If the application circuit requires non-inverted output, these devices are not suitable without circuit redesign. GTL2012DP,118 maintains the non-inverted output characteristic of the original part.
