Product details
Overview
GTL2034PW,118 from NXP Semiconductors is a 4-bit GTL-to-GTL bus buffer in TSSOP14 package, operating from 3.0 V to 3.6 V with 3.6 V-tolerant GTL I/O, adjustable VREF (0.5 V to VCC/2), and propagation delays as low as 2.8 ns (tPLH typ). It serves as a level-shifting interface between GTL-/GTL/GTL+ buses in high-speed backplane and motherboard interconnects.
For engineers reviewing the GTL2034PW,118 datasheet, GTL2034PW,118 pinout, GTL2034PW,118 application, or GTL2034PW,118 equivalent, key selection criteria include GTL-compatible voltage thresholds, partial power-down capability, ESD robustness (2000 V HBM), and compatibility with -40 °C to +85 °C industrial temperature operation.
Technical Context
The GTL2034PW,118 implements a unidirectional 4-bit GTL buffer with independent input and output stages referenced to a user-adjustable VREF pin (0.5 V to VCC/2), enabling precise threshold control for GTL-, GTL, and GTL+ signaling standards. Its architecture supports open-drain-like behavior with active pull-down and passive termination, requiring external VTT biasing.
It features partial power-down functionality-unused inputs can be held HIGH or LOW without disabling the entire device-and integrates latch-up protection exceeding 500 mA per JESD78. All GTL I/O pins tolerate up to 3.6 V regardless of VCC, supporting mixed-voltage system interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC range | 3.0 V to 3.6 V - defines valid supply window for stable GTL logic levels and timing compliance |
| tPLH / tPHL | 2.8 ns / 5.2 ns typ (GTL- mode) - enables ≤350 MHz bus operation with controlled skew |
| VREF range | 0.5 V to VCC/2 - sets input threshold (Vth±) and directly determines GTL- / GTL / GTL+ compatibility |
| IOH / IOL | ±1 μA input/output leakage - ensures minimal loading on source/sink nodes during idle states |
| ESD rating | 2000 V HBM, 200 V MM, 1000 V CDM - meets industrial-grade handling requirements without additional protection circuitry |
| Operating temp | -40 °C to +85 °C - qualified for extended industrial environments including telecom line cards and server motherboards |
| Input capacitance | 4.5 pF max - limits signal degradation and reflection on high-speed GTL stubs |
Pinout & Package
TSSOP14 package (SOT402-1), plastic thin shrink small outline, 14-lead, 4.4 mm body width, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | Not connected | No internal connection; must remain unconnected on PCB |
| VCC | Positive supply | 3.0–3.6 V main power rail; bypassing required near pin for noise suppression |
| BO0–BO3 | Data outputs (GTL) | Active-low buffered outputs; require external VTT termination at 0.9–1.65 V |
| BI0–BI3 | Data inputs (GTL) | Threshold-controlled by VREF; accept GTL- (0.6 V), GTL (0.8 V), or GTL+ (1.0 V) logic levels |
| VREF | Reference voltage input | Adjusts input switching thresholds; sets Vth+ and Vth− per Figure 3 curves |
| GND | Ground (0 V) | Three dedicated pins (7, 8, 11) - ensure low-inductance return path for all I/O and supply |
Key Features
| Feature | Design Value |
|---|---|
| GTL standard compatibility | Supports GTL-, GTL, and GTL+ signaling via programmable VREF, eliminating need for multiple buffer families |
| 3.6 V I/O tolerance | Enables safe interfacing with higher-voltage GTL drivers even when VCC = 3.0 V, simplifying mixed-rail designs |
| Partial power-down | Allows individual input biasing (HIGH/LOW) without disabling outputs - critical for hot-swap and dynamic bus partitioning |
| Low propagation skew | Matched tPLH/tPHL across all 4 channels (<1 ns typical variation) maintains data eye integrity in parallel bus applications |
| Industrial temperature range | Rated from -40 °C to +85 °C - validated for continuous operation in base station backplanes and network switch fabrics |
Applications
| Backplane Interconnect | Server Memory Bus |
|---|---|
|

IC Role / Device Role / Timing Role: Voltage-level translator and bus buffer ensuring GTL-compatible thresholds while operating from standard 3.3 V rail. Use Value: Eliminates need for discrete resistor networks or active translators; VREF adjustment allows fine-tuning to match field-installed GTL terminations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar GTL bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GTL2034PWZ | Same die, identical electrical specs; differs only in packaging (SSB static shielding bag vs. standard reel) | Drop-in replacement per NXP discontinuation notice; identical thermal, timing, and reliability performance | Select GTL2034PWZ for new designs requiring ESD-safe handling; no layout or schematic change needed |
| SN74GTL2034PWR | TI variant with same pinout and function but tighter tPHL spec (3.6 ns typ vs. 4.1 ns) and lower ICC (2.5 mA max vs. 8 mA) | Valid for GTL+ systems requiring sub-4 ns propagation; not qualified for -40 °C operation per published datasheet | Prefer SN74GTL2034PWR only if lower quiescent current and faster tPHL are critical and ambient stays ≥0 °C |
Compared with GTL2034PW,118, GTL2034PWZ offers identical functionality with enhanced ESD handling, while SN74GTL2034PWR trades industrial temperature support for marginally better speed and power efficiency in commercial environments.

FAQ
What is the maximum allowable VREF voltage for GTL2034PW,118?
The maximum VREF voltage for GTL2034PW,118 is VCC / 2. With VCC = 3.6 V, this yields 1.8 V - however, the recommended operating range is 0.5 V to 1.10 V (GTL+ mode), and exceeding 1.10 V may shift thresholds beyond GTL specification compliance. Always reference Table 7 for VREF limits per signaling mode.
Is GTL2034PW,118 pin-compatible with GTL2034PWZ?
Yes, GTL2034PW,118 and GTL2034PWZ share identical die, pinout, electrical characteristics, and thermal behavior. The only difference is packaging: GTL2034PWZ ships in a static-shielding bag (SSB), while GTL2034PW,118 uses standard reel packaging. No PCB or schematic changes are required when substituting GTL2034PWZ for GTL2034PW,118.
Can GTL2034PW,118 operate with VCC = 2.5 V?
No. GTL2034PW,118 is specified only for VCC = 3.0 V to 3.6 V per Table 7. Operation below 3.0 V violates recommended conditions and risks failure to meet GTL threshold specifications (e.g., VIL/VIL margins collapse), propagation delay guarantees, and output drive strength. Do not use GTL2034PW,118 at 2.5 V.
What is the purpose of the n.c. pin on GTL2034PW,118?
Pin 1 of GTL2034PW,118 is marked n.c. (not connected) and has no internal bond wire or circuit connection. It must remain unconnected on the PCB layout. Routing traces or placing vias to this pin may introduce parasitic coupling or contamination risk; leave it floating and unstubbed per NXP's pin configuration diagram (Figure 2).
Does GTL2034PW,118 support bidirectional data flow?
No. GTL2034PW,118 is a unidirectional 4-bit buffer: BI0–BI3 are dedicated inputs and BO0–BO3 are dedicated outputs. There is no direction-control pin or internal bus-switching logic. For bidirectional GTL translation, separate transmit/receive buffers or a different device family (e.g., GTL200x transceivers) must be used.
