Product details
Overview
GTL2003PW from NXP Semiconductors is an 8-bit bidirectional NMOS pass-transistor voltage translator IC enabling seamless level shifting between 0.8 V and 5.0 V buses without direction control. It features 6.5 Ω typical ON-state resistance, <5.5 ns propagation delay, and operates across −40 °C to +85 °C. It is used in I²C-bus interface translation between low-voltage processors (e.g., 1.2 V/1.8 V) and 3.3 V/5.0 V peripherals.
For engineers reviewing the GTL2003PW datasheet, GTL2003PW pinout, GTL2003PW application, or GTL2003PW equivalent, this page delivers verified specifications, TSSOP20 package details, bidirectional clamping behavior, ESD robustness (2000 V HBM), and real-world I²C and GTL/GTL+ translation use cases - all confirmed from NXP's official Rev. 2 product data sheet.
Technical Context
The GTL2003PW implements Gunning Transceiver Logic–Transceiver Voltage Clamp (GTL-TVC) architecture using eight matched NMOS pass transistors plus a reference transistor (SREF/DREF/GREF). Its operation relies on gate biasing: GREF must be ≥1.5 V above SREF to enable translation, with VT = SREF defining the clamped HIGH-level output on the low-voltage side.
It supports three modes - bidirectional, unidirectional HIGH-to-LOW, and unidirectional LOW-to-HIGH - each requiring specific external pull-up resistor configurations. No power supply is needed; translation is passive and latch-up free, with 5 V-tolerant inputs and inherent ESD protection exceeding JESD22-A114 (2000 V HBM) and JESD22-C101 (1000 V CDM).
Key Specifications

Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, body width 4.4 mm, 0.65 mm pitch, maximum height 1.1 mm. Exposed pad not present - standard leaded package suitable for reflow soldering per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Device ground reference; must be connected to system 0 V for proper biasing and ESD path |
| 2 | SREF | Source of reference transistor; sets clamped HIGH voltage (VT) on Sn side (e.g., 1.2 V or 1.8 V) |
| 3–10 | S1–S8 | Low-voltage-side source terminals; connect to 0.8–2.5 V processor or ASIC I/O |
| 11–18 | D1–D8 | High-voltage-side drain terminals; connect to 2.5–5.0 V peripheral or bus lines (e.g., I²C SDA/SCL) |
| 19 | DREF | Drain of reference transistor; tied to D-side VDD1 (e.g., 3.3 V) via 200 kΩ pull-up for stable bias |
| 20 | GREF | Gate of reference transistor; tied to DREF to enable NMOS conduction when DREF is HIGH |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input (S1–S8) and output (D1–D8) pins arranged linearly on opposite sides - simplifies PCB trace routing and minimizes crosstalk |
| Matched transistor characteristics | All eight Sn/Dn pairs exhibit identical Ron and propagation delay - eliminates inter-channel skew in multi-bit buses like I²C |
| Hot-insertion support | No power supply or initialization sequence required - enables safe live insertion into powered backplanes or hot-swap systems |
| Reference transistor flexibility | SREF/DREF/GREF can be implemented using any of the eight Sn/Dn pairs - allows layout optimization without dedicated reference pins |
| Open-drain compatible | Supports direct connection to open-drain I²C-bus nodes without external direction logic or bus arbitration circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NVT2003DP,118 | Lower Ron (4 Ω typ), smaller XSON10 package (2.5 × 1.0 mm), requires VCC supply (1.65–5.5 V) | Better for space-constrained, high-speed (<100 MHz) applications; not supply-free like GTL2003PW | Select when board area is critical and a local VCC rail is available; avoid if true passive operation is required. |
| PCA9306DCUR | 2-bit translator, 5 V tolerant, supports 1.2–3.3 V ↔ 1.8–5.5 V, requires dual VREF rails, 6.5 ns max tPD | Designed for I²C/SMBus only; lacks 8-bit channel count and GTL-specific biasing for sub-1 V operation | Choose for dedicated 2-channel I²C isolation where dual-reference flexibility outweighs channel density needs. |
Compared with NVT2003DP,118 and PCA9306DCUR, the GTL2003PW uniquely delivers 8-channel passive translation with no supply, sub-1 V compatibility, and flow-through TSSOP20 layout - making it optimal for industrial I²C expansion and GTL legacy integration where simplicity and robustness are prioritized over miniaturization or dual-rail flexibility.

FAQ
Does the GTL2003PW require a power supply to operate?
No, the GTL2003PW operates passively without any VDD connection. It relies solely on external pull-up resistors on the D-side (e.g., 200 kΩ to 3.3 V) and proper biasing of SREF to establish the translation threshold. This eliminates supply noise coupling and simplifies power domain isolation in mixed-voltage designs - a key advantage confirmed in Section 2 and 8.1 of the NXP datasheet for GTL2003PW.
What is the minimum voltage the GTL2003PW can translate from or to?
The GTL2003PW supports translation down to 0.8 V on either side, as explicitly stated in the General Description and Table 2 of the datasheet. Voltages below 0.8 V are possible with careful biasing but are not guaranteed. The device is validated for 0.8 V ↔ 5.0 V bidirectional operation, covering common low-voltage logic families including 0.8 V GTL, 1.2 V, 1.8 V, and 3.3 V LVTTL - all confirmed in Sections 1, 2, and 10 of the GTL2003PW product data sheet.
Can the GTL2003PW be used for I²C-bus level translation?
Yes, the GTL2003PW is explicitly recommended for I²C-bus translation in Section 3 and Figure 4 of the datasheet. Its open-drain compatible design, bidirectional operation without direction control, and sub-5.5 ns propagation delay preserve I²C timing margins for standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes. The flow-through pinout also simplifies routing of SDA/SCL pairs - a design benefit highlighted in the Features section for GTL2003PW.
How does the reference transistor (SREF/DREF/GREF) function in the GTL2003PW?
In the GTL2003PW, the reference transistor sets the clamping voltage (VT = SREF) on the low-voltage side. When GREF is pulled HIGH (tied to DREF), the NMOS pass transistors conduct, limiting Sn-side HIGH levels to SREF. For example, setting SREF to 1.2 V ensures Sn outputs never exceed 1.2 V - protecting 1.2 V processor I/O. This mechanism is detailed in Tables 4–5 and Section 7.1 of the GTL2003PW datasheet, and requires GREF ≥ SREF + 1.5 V for reliable operation.
Is the GTL2003PW pin-compatible with other packages in the GTL2003 family?
No, the GTL2003PW (TSSOP20, SOT360-1) is not pin-compatible with the GTL2003BQ (DHVQFN20, SOT764-1), despite sharing identical functionality and electrical specs. Pin numbering and physical layout differ significantly - e.g., S1–S8 occupy pins 3–10 in TSSOP20 but pins 3–10 are assigned to D7, S6, S7, D6, etc. in DHVQFN20 per Figures 2–3. Board layout must be redesigned when switching packages, as confirmed in the Pinning Information section of the GTL2003PW datasheet.
