Product details
Overview
GTL2002DP/DG,118 from NXP Semiconductors is a 2-bit bidirectional low-voltage translator IC using NMOS pass transistors to enable seamless voltage level translation between 1.0 V and 5.0 V buses without direction control. It features 6.5 Ω typical ON-state resistance, <5.5 ns propagation delay (tPLH/tPHL), and supports I²C-bus, GTL/GTL+, LVTTL/TTL, and 5 V CMOS interfaces in processor-to-chipset interconnects.
For engineers reviewing the GTL2002DP/DG,118 datasheet, GTL2002DP/DG,118 pinout, GTL2002DP/DG,118 application, or GTL2002DP/DG,118 equivalent, this device delivers verified bidirectional clamping operation, ESD-hardened (2000 V HBM) performance, flow-through pinout for PCB routing efficiency, and compatibility with hot-insertion systems requiring no power supply or latch-up immunity.
Technical Context
The GTL2002DP/DG,118 implements Gunning Transceiver Logic – Transceiver Voltage Clamp (GTL-TVC) architecture with two matched NMOS pass transistors (S1/D1 and S2/D2) and a reference transistor (SREF/DREF/GREF). Translation direction is determined dynamically by relative voltage levels on Sn and Dn ports, eliminating need for external direction signals.
Operation relies on gate biasing of GREF ≥ VSREF + 1.5 V to enable clamping; SREF sets the upper output limit on Sn side, while Dn is pulled to VCC via external resistors. All transistors are fabricated identically, ensuring minimal mismatch (<100 mV voltage deviation, <0.5 ns propagation skew) across channels.
Key Specifications

Pinout & Package
TSSOP8 package (SOT505-1): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm lead pitch, flow-through pinout optimized for PCB trace routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Common return path for all internal transistors; must be connected to system ground plane for stable clamping threshold. |
| 2 SREF | Reference source terminal | Connects to processor core supply (e.g., 1.2 V or 1.8 V); sets maximum output voltage on S1/S2 ports. |
| 3 S1 | Low-voltage I/O port A | Bidirectional data path for 1.0–1.8 V domain; follows D1 when LOW, clamped to SREF when HIGH. |
| 4 S2 | Low-voltage I/O port B | Independent second channel matching S1; enables dual-signal translation (e.g., I²C SDA/SCL). |
| 5 D2 | High-voltage I/O port B | Bidirectional path for 3.3 V/5.0 V domain; pulled to VCC via external resistor, driven LOW by S2. |
| 6 D1 | High-voltage I/O port A | Matches D2 functionality; supports parallel translation of two independent signals across voltage domains. |
| 7 DREF | Reference drain terminal | Connected to higher-voltage VCC (3.3 V–5.5 V) via 200 kΩ pull-up; establishes bias for reference transistor. |
| 8 GREF | Reference gate terminal | Internally tied to DREF; sets conduction state of reference transistor - must be ≥ VSREF + 1.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| No-direction-pin operation | Eliminates GPIO overhead and timing-critical direction control logic in SoC/FPGA designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP GTL2002D,118 | SO8 package (3.9 mm width) vs. TSSOP8 (3.0 mm); identical electrical specs and pinout mapping. | Better thermal dissipation and hand-solderability; less suitable for ultra-dense PCBs. | Select GTL2002D,118 for prototyping, manual assembly, or thermal-limited environments. |
| Texas Instruments TXS0102DCUR | Active push-pull architecture requiring VCCA/VCCB supplies; 10 µA quiescent current vs. zero supply for GTL2002DP/DG,118. | Supports higher drive strength (±24 mA) but adds power management complexity and layout overhead. | Choose TXS0102DCUR only when active drive and configurable auto-direction are required; GTL2002DP/DG,118 remains optimal for passive, zero-power use cases. |
Compared with GTL2002D,118, the GTL2002DP/DG,118 offers identical functionality in a space-saving TSSOP8 footprint, while TXS0102DCUR introduces supply dependencies and higher static current - making GTL2002DP/DG,118 the preferred choice for ultra-low-power, supply-constrained, or thermally sensitive designs.

FAQ
Does GTL2002DP/DG,118 require a power supply to operate?
No, GTL2002DP/DG,118 operates passively without any VCC connection. It uses external pull-up resistors on Dn ports and a reference voltage on SREF to enable bidirectional clamping. This eliminates power rail dependencies, reduces BOM count, and supports true zero-power system states - a key advantage over active translators like TXS0102DCUR that require dual supplies.
What is the maximum recommended clamp current per channel for GTL2002DP/DG,118?
The absolute maximum clamp current per channel is ±128 mA, but the recommended operating condition specifies IPASS ≤ 64 mA. For reliable VOL ≤ 350 mV, design with ≤15 mA per channel using pull-up resistors sized per Table 6 - e.g., 310 Ω for 5.0 V VCC and 15 mA. Exceeding 15 mA increases pass voltage nonlinearly and risks thermal overstress in sustained operation.
Can GTL2002DP/DG,118 translate between 1.0 V and 5.0 V in both directions simultaneously?
Yes - GTL2002DP/DG,118 supports true simultaneous bidirectional translation. When S1 is driven LOW by a 1.0 V processor, D1 is pulled LOW through the ON-state transistor; when D1 is driven HIGH by a 5.0 V peripheral, S1 is clamped to VSREF (e.g., 1.0 V). This occurs independently on both channels without direction pin intervention or timing arbitration.
Is GTL2002DP/DG,118 compatible with I²C-bus open-drain topology?
Yes, GTL2002DP/DG,118 is explicitly designed for I²C-bus applications. Its open-drain–compatible clamping behavior preserves bus arbitration, supports multi-master operation, and maintains standard I²C timing margins - confirmed in Figure 6 and Section 8.1 of the datasheet. External pull-ups on Dn ports are mandatory, matching standard I²C implementation requirements.
What package variant does GTL2002DP/DG,118 use, and how does it differ from GTL2002D,118?
GTL2002DP/DG,118 uses the TSSOP8 package (SOT505-1), measuring 3.0 mm body width with 0.65 mm lead pitch. In contrast, GTL2002D,118 uses SO8 (SOT96-1) with 3.9 mm width. Both share identical pinout, electrical specs, and thermal ratings, but TSSOP8 enables higher PCB density - critical for space-constrained modules like PCIe add-in cards or compact baseband units where GTL2002DP/DG,118 is commonly deployed.
