Product details
Overview
GTL2002DP/S440,118 from NXP Semiconductors is a 2-bit bidirectional low-voltage translator IC enabling seamless voltage level translation between 1.0 V and 5.0 V buses without direction control. It features two matched NMOS pass transistors (S1/D1 and S2/D2), a reference transistor (SREF/DREF/GREF), 6.5 Ω typical ON-state resistance at 4.5 V gate drive, <5.5 ns propagation delay, and operates across −40 °C to +85 °C. It is used in I²C-bus voltage translation between 1.8 V processors and 3.3 V/5 V peripherals.
For engineers reviewing the GTL2002DP/S440,118 datasheet, GTL2002DP/S440,118 pinout, GTL2002DP/S440,118 application, or GTL2002DP/S440,118 equivalent, key selection criteria include bidirectional clamping operation without direction pin, 5 V-tolerant inputs, flow-through TSSOP8 pinout, ESD robustness (2000 V HBM), and compatibility with GTL, LVTTL, TTL, and CMOS logic families.
Technical Context
The GTL2002DP/S440,118 implements Gunning Transceiver Logic–Transceiver Voltage Clamp (GTL-TVC) architecture using symmetrical NMOS transistors for precise bidirectional voltage translation. Its reference transistor (SREF/DREF/GREF) sets the clamp voltage on the low-voltage side, while GREF must be ≥1.5 V above SREF for optimal operation.
It supports both HIGH-to-LOW and LOW-to-HIGH translation modes via external pull-up configuration on DREF and SREF connection to core supply. No power supply is required; operation relies solely on signal-level biasing, eliminating latch-up risk and enabling hot insertion.

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 (SOT96-1), 3.9 mm body width vs. TSSOP8's 3.0 mm; identical electrical specs | Preferred for through-hole prototyping or legacy SO8 footprints; lower thermal resistance than TSSOP8 | Select when board space permits larger footprint or reflow compatibility with existing SO8 tooling is required |
| Texas Instruments TXS0102DCUR | Active push-pull translation (not passive clamp); requires VCCA/VCCB supplies; 10 µA quiescent current vs. near-zero for GTL2002DP | Supports higher drive strength (±24 mA) but adds power dependency and complexity for simple clamping use cases | Choose only if active drive capability or guaranteed rail-to-rail output swing is mandatory; otherwise GTL2002DP offers simpler, supply-free operation |
Compared with GTL2002D,118, the GTL2002DP/S440,118 saves PCB area with its 3 mm-wide TSSOP8 package while retaining identical performance; versus TXS0102DCUR, it eliminates supply rails and static current draw, making it ideal for ultra-low-power or supply-constrained systems where passive clamping suffices.

FAQ
Does GTL2002DP/S440,118 require a power supply to operate?
No, GTL2002DP/S440,118 is a passive voltage clamp device and requires no VCC or power rail. It operates entirely from signal-level biasing-GREF and DREF are pulled to the higher-voltage side (e.g., 3.3 V), while SREF connects to the lower-voltage core supply (e.g., 1.8 V). This eliminates standby current and latch-up risk, making GTL2002DP/S440,118 ideal for always-on or energy-sensitive systems.
What is the maximum recommended clamp current per channel for GTL2002DP/S440,118?
The absolute maximum clamp current per channel for GTL2002DP/S440,118 is ±128 mA, but the recommended operating limit is 64 mA to maintain VOL ≤350 mV. At 15 mA clamp current, typical pass voltage is 260–350 mV-this ensures reliable LOW-level signaling while avoiding excessive heating. External pull-up resistors must be sized accordingly (e.g., 310 Ω for 5 V, 197 Ω for 3.3 V) per Table 6 in the datasheet.
Can GTL2002DP/S440,118 translate between 1.0 V and 5.0 V in both directions simultaneously?
Yes, GTL2002DP/S440,118 supports true simultaneous bidirectional translation between 1.0 V and 5.0 V, provided GREF is ≥1.5 V above SREF and DREF is pulled to the 5.0 V rail. When S1 is driven LOW by a 1.0 V device, D1 is pulled LOW through the ON-state transistor; when D1 is HIGH (5.0 V), S1 is clamped to the SREF voltage (e.g., 1.0 V). This enables real-time, contention-free I²C-style communication without direction control.
Is GTL2002DP/S440,118 compatible with open-drain I²C buses?
Yes, GTL2002DP/S440,118 is explicitly optimized for open-drain I²C-bus translation. Its passive clamp architecture naturally complements open-drain topologies: no external direction control is needed, and pull-up resistors on the higher-voltage side (D1/D2) ensure proper HIGH-level restoration. The device's low Ron and fast propagation delay preserve I²C timing margins even at 400 kHz and 1 MHz standard/fast-mode speeds.
How does GTL2002DP/S440,118 provide ESD protection to connected devices?
GTL2002DP/S440,118 integrates on-die ESD protection diodes on all Sn/Dn pins rated to 2000 V HBM (JESD22-A114) and 1000 V CDM (JESD22-C101). During an ESD event, transient current is shunted through these diodes to GND or the local rail, preventing voltage overshoot beyond safe limits on sensitive 1.0 V–1.8 V processor I/O. This eliminates the need for discrete TVS diodes in many space-constrained designs.
