Product details
Overview
GTL2005PW,112 from NXP Semiconductors is a quad GTL/GTL+ to LVTTL/TTL bidirectional non-latched translating transceiver operating at 3.0–3.6 V with 5 V-tolerant B-side I/O, enabling interface between 3.3 V GTL/GTL+ buses and 5 V TTL/LVTTL logic in high-speed backplane or motherboard applications.
For engineers reviewing the GTL2005PW,112 datasheet, GTL2005PW,112 pinout, GTL2005PW,112 application, or GTL2005PW,112 equivalent, key selection factors include direction-controlled bidirectional translation, VREF-dependent GTL threshold linearity down to 0.5 V, propagation delays as low as 1.9 ns (B→A), 5 V tolerance on TTL-side pins, and TSSOP14 package compatibility with dense PCB layouts.
Technical Context
The GTL2005PW,112 implements a non-latched, direction-controlled architecture where DIR pin state determines signal flow: HIGH enables GTL sampling receiver mode (B→A), LOW enables TTL-to-GTL driver mode (A→B). It supports GTL−, GTL, and GTL+ standards via configurable VREF (0.5–1.8 V).
Its A-side (GTL) inputs/outputs operate referenced to VREF with thresholds VTH+ and VTH− varying per VREF and temperature; B-side (TTL) pins tolerate up to 5.5 V and drive ±12 mA at 3.0 V supply, while ICC remains ≤3 mA under static conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3.0 V to 3.6 V - ensures stable operation across industrial-grade 3.3 V rail tolerances. |
| B-Side Input Tolerance | Up to 5.5 V - allows direct connection to legacy 5 V TTL/CMOS without level-shifting circuitry. |
| Min tPHL (B→A) | 1.9 ns at VCC = 3.3 V - enables sub-2 ns propagation for high-frequency GTL bus sampling. |
| VREF Range | 0.5 V to 1.8 V - supports GTL− (0.6 V), GTL (0.8 V), and GTL+ (1.0 V) standards via external reference. |
| ESD Protection | 2000 V HBM - meets JEDEC JESD22-A114 for robust handling in manufacturing and field environments. |
| Package | TSSOP14 (SOT402-1), 4.4 mm body width - provides compact footprint for space-constrained board designs. |
| IOL (B port) | 128 mA max - sustains high-current drive into terminated GTL bus loads without voltage droop. |
Pinout & Package
TSSOP14 package (SOT402-1), plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DIR (Pin 1) | Direction control input | Active-HIGH selects B→A GTL sampling; active-LOW selects A→B TTL driving - no latching, real-time flow control. |
| A0–A3 (Pins 2,3,5,6) | GTL-side I/O | Interface directly with GTL/GTL+ bus; referenced to VREF; thresholds degrade below 0.8 V per datasheet Section 10.1. |
| B0–B3 (Pins 9,10,12,13) | TTL-side I/O | 5 V tolerant; drive/receive LVTTL/TTL signals; support live insertion/extraction per functional description. |
| VREF (Pin 4) | GTL reference voltage input | Sets GTL switching thresholds; must be externally supplied; nominal 2/3×VTT (e.g., 0.8 V for GTL). |
| VCC (Pin 14) | Positive supply | 3.0–3.6 V only; powers internal logic and output stages; not used for B-side voltage translation. |
| GND (Pins 7,8,11) | Ground reference | Three dedicated ground pins minimize ground bounce in high-speed bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad bidirectional translation | Four independent A↔B channels controlled by single DIR pin - reduces component count vs. discrete translators. |
| 5 V-tolerant LVTTL I/O | B-side pins withstand 5.5 V input while powered from 3.3 V - eliminates need for external clamping diodes. |
| Live insertion/extraction support | Enabled by power-up/down sequencing tolerance and I/O protection - suitable for hot-pluggable backplane modules. |
| Latch-up immunity | Exceeds 500 mA per JESD78 - prevents destructive latch-up during transient overvoltage events. |
| Low capacitance I/O | A-port Cio ≤5.0 pF, B-port Cio ≤7.0 pF - minimizes signal loading on high-speed GTL and TTL buses. |
Applications
| Server Backplane Interconnect | Industrial PLC I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GTL/GTL+ to TTL bidirectional translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GTL2014PW,118 | Lower propagation delay (1.4 ns B→A), optimized for GTL+/GTL− only; no VREF flexibility below 0.8 V. | Better suited for high-speed GTL+ clock distribution where VREF ≥0.8 V is guaranteed. | Select GTL2014PW,118 when minimizing tPHL is critical and VREF stability >0.8 V can be ensured. |
| SN74AVC4T245RGYR | 3.3 V–1.2 V dual-supply translation; no GTL-specific thresholds; CMOS-based, not GTL-compliant. | Applicable only for generic voltage-level shifting, not GTL/GTL+ bus compliance or noise margin optimization. | Choose SN74AVC4T245RGYR for non-GTL mixed-voltage logic interfacing where GTL specification adherence is unnecessary. |
Compared with GTL2005PW,112, GTL2014PW,118 offers faster propagation but reduced VREF flexibility, while SN74AVC4T245RGYR provides broader voltage range support at the cost of GTL electrical compliance and noise margin guarantees.

FAQ
What is the minimum recommended VREF voltage for reliable operation of the GTL2005PW,112?
The GTL2005PW,112 VREF linearity degrades below 0.8 V per Section 10.1 of the datasheet. While the absolute minimum VREF is specified as 0.5 V, operation below 0.8 V requires careful noise margin analysis. For GTL− applications, 0.6 V is usable but demands tighter layout control; for GTL and GTL+, 0.8 V and 1.0 V respectively are strongly recommended. The GTL2005PW,112 must be evaluated against actual system noise in each case.
Can the GTL2005PW,112 interface directly with 5 V microcontrollers without external components?
Yes - the B-side (TTL) pins of the GTL2005PW,112 are 5 V tolerant up to 5.5 V, allowing direct connection to 5 V microcontroller I/Os when VCC is 3.3 V. No series resistors or clamping diodes are required. However, the DIR pin must be driven from a 3.3 V logic source, and VREF must be externally supplied at the appropriate level (e.g., 0.8 V for GTL) to ensure correct GTL threshold behavior on the A side.
Does the GTL2005PW,112 support hot-swap or live insertion functionality?
Yes - the GTL2005PW,112 explicitly supports live insertion/extraction as stated in its Features section. This capability stems from its robust ESD protection (2000 V HBM), latch-up immunity (>500 mA), and I/O structure that tolerates floating or unpowered states during insertion. To maintain reliability, ensure proper power sequencing (VCC applied before signals) and follow NXP's AN10365 reflow guidelines for TSSOP14 soldering.
How does the DIR pin control data flow direction in the GTL2005PW,112?
In the GTL2005PW,112, the DIR pin is an active-HIGH control: when DIR = HIGH, signals pass from B-side (TTL) to A-side (GTL) - functioning as a GTL sampling receiver; when DIR = LOW, signals pass from A-side (GTL) to B-side (TTL) - functioning as a TTL-to-GTL driver. The device is non-latched, so direction changes occur dynamically with DIR state transitions, with propagation delays specified separately for each path (e.g., 1.9 ns tPHL B→A, 4.4 ns tPHL A→B).
What are the thermal limitations for continuous operation of the GTL2005PW,112?
The GTL2005PW,112 has a maximum junction temperature of 150 °C per Section 8 Limiting Values. Its ambient operating range is −40 °C to +85 °C. With typical ICC ≤3 mA and low dynamic power, self-heating is minimal in standard PCB layouts. However, simultaneous sourcing of 128 mA per B-port output at high duty cycles requires attention to copper pour and thermal vias under the TSSOP14 package to avoid exceeding TJ(max); derating is advised above 70 °C ambient when driving heavy loads.
