Product details
Overview
GTL2034PW,112 from NXP Semiconductors (formerly Philips Semiconductors) is a 4-bit GTL−/GTL/GTL+ bus buffer IC designed for high-speed signal translation in backplane and motherboard interconnects. It operates from 3.0 V to 3.6 V, supports 3.6 V-tolerant GTL I/O, features adjustable VREF (0.5 V to VCC/2), and delivers propagation delays as low as 2.8 ns (tPLH, GTL− mode). It is used in server memory subsystems requiring level-shifted, low-skew data buffering between GTL-compatible ASICs.
For engineers reviewing the GTL2034PW,112 datasheet, GTL2034PW,112 pinout, GTL2034PW,112 application, or GTL2034PW,112 equivalent, key selection criteria include GTL family compatibility, VREF adjustability for threshold tuning, partial power-down capability, ESD robustness (2000 V HBM), and TSSOP14 package suitability for dense PCB layouts.
Technical Context
The GTL2034PW,112 implements a unidirectional, non-inverting 4-bit GTL-to-GTL buffer with separate input and output ports (BI0–BI3 and BO0–BO3). Its VREF pin enables precise adjustment of input switching thresholds across GTL− (0.6 V), GTL (0.8 V), and GTL+ (1.0 V) standards, ensuring reliable operation under varying termination voltages (VTT = 0.9 V / 1.2 V / 1.5 V).
It supports partial power-down: unused inputs must be held HIGH or LOW, and outputs remain high-impedance when disabled. The device meets JESD22-A114 (2000 V HBM), JESD22-A115 (200 V MM), and JESD22-C101 (1000 V CDM) ESD specifications, and latch-up immunity exceeds 500 mA per JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 3.0 V to 3.6 V - Enables direct integration into 3.3 V systems with margin for rail tolerance |
| VREF range | 0.5 V to VCC/2 - Allows dynamic threshold calibration for GTL−, GTL, and GTL+ signaling standards |
| tPLH / tPHL | 2.8 ns / 5.2 ns (GTL−); 3.1 ns / 4.1 ns (GTL); 3.3 ns / 3.6 ns (GTL+) - Ensures sub-10 ns timing integrity in high-frequency bus applications |
| Input capacitance | 4.5 pF - Minimizes loading on upstream GTL drivers, preserving signal edge rate |

| Operating temperature | −40 °C to +85 °C - Qualified for industrial-grade motherboard and telecom infrastructure use |
| ESD rating | 2000 V HBM - Provides robust handling margin during board assembly and system integration |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14-lead, body width 4.4 mm, lead pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | No-connect | Pin 1 is internally unused; must be left floating or grounded per layout best practice |
| BO0–BO3 | Data outputs (GTL) | Active-drive GTL outputs; each capable of sourcing/sinking up to 40 mA into VTT-terminated loads |
| BI0–BI3 | Data inputs (GTL) | 3.6 V-tolerant GTL inputs; switching threshold set by external VREF voltage |
| VREF | Reference voltage input | Analog control node setting input hysteresis and logic thresholds for all four channels |
| VCC | Positive supply | 3.0–3.6 V core supply; powers internal logic and output drivers |
| GND | Ground | Pins 7, 8, and 11 provide low-inductance return paths for signal and supply currents |
Key Features
| Feature | Design Value |
|---|---|
| GTL family compatibility | Supports GTL−, GTL, and GTL+ standards via single VREF adjustment - eliminates need for multiple buffer variants |
| Adjustable input threshold | VREF programmable from 0.5 V to VCC/2 - enables precise matching to system VTT and noise margin requirements |
| Partial power-down | Unused inputs must be terminated HIGH/LOW - prevents floating inputs while allowing selective channel disable |
| 3.6 V I/O tolerance | GTL inputs and outputs withstand up to 3.6 V - allows interoperability with higher-voltage open-drain drivers |
| Low propagation skew | Matched tPLH/tPHL across all 4 channels - maintains signal alignment critical for parallel bus timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GTL bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74GTL2034PWR | TI variant with identical pinout, same 3.0–3.6 V operation, but VREF range limited to 0.5 V–0.9 V; tPLH/tPHL slightly higher (3.5 ns/4.5 ns typ) | Less flexible for GTL+ (1.5 V VTT) systems due to narrower VREF range | Select when sourcing TI-qualified supply chain or requiring TI's enhanced thermal derating documentation |
| 74GTLP2204APW | NXP variant with 8-bit capacity, same TSSOP14 package, identical VREF adjustability and ESD ratings, but higher ICC (12 mA max) | Provides double channel count in same footprint - suitable for wider buses but increases quiescent current | Select when expanding bus width without changing layout; verify PCB thermal margin for +4 mA extra supply current |
Compared with SN74GTL2034PWR, GTL2034PW,112 offers broader VREF tuning (up to VCC/2) for GTL+ compliance, while 74GTLP2204APW trades channel count for footprint reuse - both require validation of VTT/VREF interaction in target system.

FAQ
What is the maximum VTT voltage supported by GTL2034PW,112?
GTL2034PW,112 supports VTT up to 3.6 V per absolute maximum ratings, but recommended operating VTT is 0.95 V (GTL−), 1.26 V (GTL), or 1.65 V (GTL+). Exceeding recommended VTT may degrade noise margin or increase ICC without improving functionality.
Can GTL2034PW,112 operate with VCC = 3.0 V and still meet GTL+ timing specs?
Yes, GTL2034PW,112 meets GTL+ timing (tPLH ≤ 8 ns, tPHL ≤ 10 ns) at VCC = 3.0 V, Vref = 1.0 V, and VTT = 1.5 V per Table 9. However, VOL rises to 0.4 V (max), requiring verification of downstream receiver VIH compatibility.
Is GTL2034PW,112 pin-compatible with GTL2004 or GTL2005 series devices?
No, GTL2034PW,112 is not pin-compatible with GTL2004 or GTL2005. Those are 8-bit buffers in SO16 or TSSOP20 packages with different pin assignments and VREF configurations. GTL2034PW,112 uses TSSOP14 with dedicated n.c. and triple-GND layout.
Does GTL2034PW,112 support hot-swap or live-insertion?
GTL2034PW,112 does not include explicit hot-swap circuitry. While its 3.6 V I/O tolerance and partial power-down aid controlled insertion, safe live-insertion requires external sequencing and current-limiting design - refer to Section 9 of the datasheet for recommended biasing during power ramp.
What is the thermal resistance (θJA) of GTL2034PW,112 in TSSOP14 package?
The datasheet does not specify θJA for GTL2034PW,112. Based on SOT402-1 package characteristics and typical TSSOP14 construction, θJA is approximately 160 °C/W on 1-layer 1-oz copper; actual value depends on PCB layout. For thermal design, assume max junction temperature of 150 °C per Section 8.
