Product details
Overview
GTL2010PW/N,118 from NXP Semiconductors is a 10-bit bidirectional NMOS pass-transistor voltage translator IC enabling seamless level shifting between 1.0 V and 5.0 V buses without direction control. It features 6.5 Ω typical ON-state resistance, sub-5.5 ns propagation delay, and supports I²C-bus, GTL/GTL+, LVTTL/TTL, and 5 V CMOS interfacing in processor-to-chipset signal translation.
For engineers reviewing the GTL2010PW/N,118 datasheet, GTL2010PW/N,118 pinout, GTL2010PW/N,118 application, or GTL2010PW/N,118 equivalent, this device delivers verified bidirectional clamping operation, ESD-hardened (2000 V HBM) performance, flow-through TSSOP24 layout compatibility, and hot-insertion support - critical for low-voltage processor I/O protection and mixed-voltage system integration.
Technical Context
The GTL2010PW/N,118 implements Gunning Transceiver Logic–Transceiver Voltage Clamp (GTL-TVC) architecture using matched NMOS pass transistors with a common reference gate (GREF) and dedicated reference transistor (SREF/DREF). Its operation relies on voltage-controlled clamping: when Dn is HIGH, Sn is limited to SREF voltage; when Sn is LOW, Dn follows via low-Ron conduction.
No external power supply is required - the device draws zero quiescent current in standby and avoids latch-up. Translation direction is inherently determined by relative port voltages and GREF/SREF biasing, eliminating need for control logic or direction pins across all supported voltage pairs (1.0 V ↔ 3.3 V, 1.2 V ↔ 5.0 V, etc.).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 10 independent bidirectional Sn/Dn channels + 1 reference pair (SREF/DREF/GREF) |
| ON-state resistance (Ron) | 6.5 Ω typical at VGREF = 3 V, IO = 30 mA - enables <350 mV voltage drop under 15 mA clamp current |
| Propagation delay | 1.5 ns typical tPLH/tPHL (Sn↔Dn) - supports >200 MHz signal translation in translator-mode applications |
| Voltage translation range | 1.0 V ↔ 5.0 V bidirectional - covers GTL (1.2 V), LVTTL (3.3 V), TTL (5 V), and sub-1.5 V core I/Os |
| ESD rating | 2000 V HBM, 200 V MM, 1000 V CDM - protects downstream 1.0–1.8 V processors from bus-level ESD events |
| Operating temperature | −40 °C to +85 °C - qualified for industrial embedded and computing motherboard environments |
| Input tolerance | 5 V tolerant on all Sn/Dn ports - allows direct connection to 5 V buses without external clamping |
Pinout & Package
TSSOP24 package (SOT355-1): plastic thin shrink small outline, 24-lead, 4.4 mm body width, 0.65 mm pitch, exposed pad not present. Pin 1 index located at top-left corner; flow-through layout minimizes PCB trace crossovers.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Common return for all internal transistors; must be connected to system ground for stable clamping threshold |
| SREF (Pin 2) | Reference source terminal | Sets maximum output voltage on Sn side; tied to processor core supply (e.g., 1.2 V or 1.5 V) |
| S1–S10 (Pins 3–12) | Low-voltage port sources | Connect to 1.0–1.8 V processor I/Os; each mirrors Dn state when active, clamped to SREF when Dn is HIGH |
| D1–D10 (Pins 13–22) | High-voltage port drains | Interface with 3.3 V/5 V chipsets; pulled to VCC via external resistors; follow Sn when LOW, float HIGH otherwise |
| DREF (Pin 23) | Reference drain terminal | Bias node for reference transistor; connected to higher-voltage VCC (3.3–5.5 V) via 200 kΩ pull-up |
| GREF (Pin 24) | Reference gate control | Drives all 10 pass transistors; must be ≥1.5 V above SREF for reliable clamping operation |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Enables true bidirectional voltage translation (e.g., 1.2 V ↔ 3.3 V I²C) without control logic or timing overhead |
| Matched transistor array | All 10 Sn/Dn channels exhibit ≤5 % Ron and propagation delay deviation - eliminates skew in parallel data buses |
| Zero-power standby | Draws no supply current; eliminates static power penalty in always-on I/O bridges and hot-swap interfaces |
| Flow-through pinout | Pins S1–S10 and D1–D10 arranged linearly on opposite sides - simplifies routing in dense BGA processor layouts |
| Hot-insertion support | Withstands live insertion into powered backplanes; no power sequencing or reset coordination needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16T245DGGR | 16-bit, dual-supply (1.2–3.6 V), direction-pin controlled, 3.5 Ω Ron, 3.2 ns delay | Requires direction control logic; unsuitable for open-drain I²C; better for wide parallel buses with known data flow | Select when deterministic unidirectional control is available and higher channel count justifies added logic complexity |
| TXB0108PWR | 8-bit, auto-direction sensing, 3.3–5.5 V supply required, 4 Ω Ron, 5.2 ns delay | Needs VCCA/VCCB supplies; auto-sensing adds 100 ns latency on direction change; not 5 V tolerant on A-side | Prefer for mixed 1.8 V/3.3 V systems where supply rails are available and direction transitions are infrequent |
Compared with SN74AVC16T245DGGR and TXB0108PWR, GTL2010PW/N,118 uniquely delivers zero-power, pinless bidirectional operation with 5 V tolerance - making it optimal for I²C, hot-plug, and ultra-low-power embedded interfaces where supply constraints or direction uncertainty exist.

FAQ
Does GTL2010PW/N,118 require an external power supply to operate?
No, GTL2010PW/N,118 operates without any VCC connection - it derives bias from the signal lines themselves. The device uses the voltage difference between SREF and DREF/GREF to enable pass-transistor conduction, resulting in zero quiescent current draw. This makes GTL2010PW/N,118 ideal for always-on I/O bridges where power budget is constrained.
What is the maximum recommended clamp current per channel for GTL2010PW/N,118?
The absolute maximum clamp current per channel is ±128 mA, but the recommended operating limit is 64 mA to maintain VOL ≤350 mV. At 15 mA clamp current - typical for I²C pull-up designs - GTL2010PW/N,118 delivers 260–350 mV VOL, ensuring robust LOW-level recognition across voltage domains while avoiding excessive heating.
Can GTL2010PW/N,118 translate between 1.0 V and 5.0 V in both directions simultaneously?
Yes, GTL2010PW/N,118 supports true simultaneous bidirectional translation between 1.0 V and 5.0 V. When SREF is set to 1.0 V and DREF/GREF to 5.0 V, Sn ports are clamped to 1.0 V during HIGH states, while Dn ports are pulled to 5.0 V via external resistors. This configuration is validated in NXP's AN10145 for I²C and GTL+ applications.
Is GTL2010PW/N,118 compatible with I²C-bus open-drain topology?
Yes, GTL2010PW/N,118 is explicitly designed for open-drain I²C-bus translation. Its lack of direction pin, inherent bidirectionality, and ability to pass LOW signals with minimal voltage drop (≤350 mV) meet I²C electrical requirements. External pull-up resistors on the Dn side (e.g., 2.2 kΩ to 3.3 V) complete the standard I²C interface.
What package type does GTL2010PW/N,118 use, and is thermal pad soldering required?
GTL2010PW/N,118 uses the TSSOP24 package (SOT355-1), which has no exposed thermal pad. Unlike HVQFN variants, this version relies on standard lead-frame conduction; no thermal vias or board-level thermal pads are required. The 4.4 mm body width and 0.65 mm pitch support fine-pitch automated assembly without special reflow profiles.
