Product details
Overview
SN74GTL2007PWR from Texas Instruments is a 12-bit bidirectional GTL-/GTL/GTL+ to LVTTL translator optimized for dual-processor platform health management. It supports 3.3-V LVTTL I/O interfacing with Xeon® processor GTL-family signals, features VREF-based threshold control (0.6–1.1 V), open-drain I/O on ports 5A/6A/11A and 7BO1/7BO2, and operates across −40°C to 85°C.
For engineers reviewing the SN74GTL2007PWR datasheet, SN74GTL2007PWR pinout, SN74GTL2007PWR application, or SN74GTL2007PWR equivalent, this page delivers verified electrical specs, validated translation behavior across GTL−/GTL/GTL+ variants, confirmed latch-up immunity per JESD78, ESD ratings up to 2000-V HBM, and precise enable-controlled output timing with glitch suppression on 7BO1/7BO2.
Technical Context
The SN74GTL2007PWR implements dual-voltage domain translation using separate reference-controlled input thresholds (VREF) for GTL-side inputs and LVTTL-compatible outputs. Its architecture includes two independent enable groups (EN1, EN2), dedicated open-drain I/O pairs (5A/5BI/6A/6BI, 11A/11BI/11BO), and a delayed-enable path for 7BO1/7BO2 to prevent transient glitches during 5A/6A switching.
It supports three GTL voltage modes: GTL− (VTT = 0.9 V, VREF = 0.6 V), GTL (VTT = 1.2 V, VREF = 0.8 V), and GTL+ (VTT = 1.5 V, VREF = 1.0 V), with propagation delays ranging from 1 ns (min) to 13 ns (max) depending on mode and signal direction. All LVTTL inputs retain high-impedance state during power-down with no leakage to VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 3.0 V to 3.6 V - Ensures compatibility with standard 3.3-V LVTTL systems without level-shifting circuitry. |
| GTL Reference Voltage (VREF) | 0.6 V (GTL−), 0.8 V (GTL), 1.0 V (GTL+) - Sets input threshold for GTL-side receivers; externally supplied and stable over temperature. |
| Output Drive Strength | 16 mA (LVTTL A-port), 15 mA (GTL B-port) - Sufficient to drive 30-Ω series-terminated GTL lines and standard LVTTL loads. |
| Propagation Delay (B→A) | 2–10 ns typical - Enables sub-10-ns bidirectional translation critical for real-time platform health signaling like PROCHOT_L and THRMTRIP_L. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - Meets industrial handling requirements and protects against board-level ESD events. |
| Latch-Up Immunity | JESD78 Class II compliant - Guarantees robust operation in noisy server/platform environments with rail-to-rail transients. |
| Operating Temperature | −40°C to +85°C - Validated for use in server motherboard and embedded computing thermal zones. |
Pinout & Package
TSSOP-28 package (PW), 4.4 mm × 9.7 mm body, 0.65 mm pitch, exposed pad not present. Pin 1 marked via top-side laser marking "GK2007".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VREF (Pin 1) | GTL reference input | Sets input threshold for all GTL-side receivers (nBn); must be externally biased to 0.6/0.8/1.0 V per GTL mode. |
| EN1 (Pin 23) | Enable for group 1 | Controls bidirectional flow on pins 1AO–2AO / 1BI–2BI; active-high, TTL-compatible. |
| EN2 (Pin 15) | Enable for group 2 | Controls bidirectional flow on pins 3AO–4AO / 3BI–4BI; includes internal delay to suppress 7BO1/7BO2 glitches. |
| nAn (Pins 2–6,8,10–13,15,23) | LVTTL I/O port | Bidirectional LVTTL interface (3.3 V); includes totem-pole outputs and high-Z inputs during power-down. |
| nBn (Pins 7,9,16–22,24–27) | GTL I/O port | Bidirectional GTL−/GTL/GTL+ interface; inputs referenced to VREF, outputs pulled to VTT via external termination. |
| VCC (Pin 28) | Positive supply | 3.3-V core supply; powers internal logic and LVTTL outputs; decoupling required within 1 cm. |
| GND (Pin 14) | Ground reference | Common return for all I/O and supply domains; must be low-inductance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable GTL mode support | Single device supports GTL−, GTL, and GTL+ via VREF selection - eliminates need for multiple part numbers in multi-platform designs. |
| Glitch-suppressed 7BO1/7BO2 enable path | Internal 100-ns delay on EN2 prevents false low pulses when 5A/6A transition - ensures reliable PROCHOT_L assertion in thermal emergency paths. |
| Power-down high-impedance inputs | All LVTTL inputs remain high-Z with zero leakage to VCC when unpowered - enables hot-swap and partial-power-down system architectures. |
| Open-drain I/O flexibility | Pins 5A/6A/11A and 7BO1/7BO2 are open-drain - allows wired-OR signaling, level-independent pull-ups, and direct connection to 1.2-V/1.5-V GTL buses. |
| JEDEC-compliant reliability | Latch-up tested per JESD78 Class II and ESD rated per JESD22 - qualified for mission-critical server health monitoring applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional GTL/LVTTL translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74GTL16212DGGR | 24-bit, 56-pin TSSOP; higher channel count, no integrated VREF buffer; requires external VREF source. | Targeted at wider data buses (e.g., address/control lines), not optimized for low-latency health signaling. | Select when scaling beyond 12 bits or requiring separate VREF control per channel group. |
| SN74AVC16T245DGGR | 16-bit AVC translator; supports 1.2–3.6 V dual-supply operation; no GTL-specific VREF or termination support. | General-purpose voltage translation only; lacks GTL timing compliance, VTT biasing, or glitch suppression. | Select for non-GTL mixed-voltage I/O where GTL waveform fidelity and JEDEC GTL timing are not required. |
Compared with SN74GTL2007PWR, SN74GTL16212DGGR offers greater channel density but adds layout complexity and lacks built-in VREF conditioning, while SN74AVC16T245DGGR provides broader voltage range support but cannot meet GTL−/GTL/GTL+ timing or termination requirements - making SN74GTL2007PWR uniquely suited for Xeon platform health management.

FAQ
What is the function of VREF on SN74GTL2007PWR?
VREF on SN74GTL2007PWR sets the input threshold voltage for all GTL-side receivers (nBn pins). It must be externally supplied at 0.6 V for GTL−, 0.8 V for GTL, or 1.0 V for GTL+ operation. This reference directly determines valid logic-high detection on GTL inputs and is critical for noise margin and timing accuracy in SN74GTL2007PWR-based interfaces.
Does SN74GTL2007PWR support hot-swap or partial power-down scenarios?
Yes - all LVTTL inputs on SN74GTL2007PWR enter a true high-impedance state with zero leakage current to VCC when the device is unpowered. This behavior is confirmed in the datasheet FAQ and enables safe hot-swap operation in modular server chassis where SN74GTL2007PWR interfaces powered-down CPUs to always-on management controllers.
How does SN74GTL2007PWR prevent glitches on 7BO1/7BO2 outputs?
SN74GTL2007PWR incorporates an internal delay (~100 ns) on the EN2 enable path to 7BO1/7BO2. This delay ensures that transitions on 5A/6A (which may lag due to RC effects) do not cause momentary low pulses on 7BO1/7BO2 - a key design feature verified in the function table note and critical for reliable PROCHOT_L signaling in SN74GTL2007PWR-based thermal management circuits.
What are the absolute maximum ratings for SN74GTL2007PWR supply and I/O voltages?
The absolute maximum supply voltage (VCC) for SN74GTL2007PWR is −0.5 V to 4.6 V. Input/output voltage limits are −0.5 V to 4.6 V on both A (LVTTL) and B (GTL) ports. Exceeding these values risks permanent damage; operation must remain within recommended ranges: VCC = 3.0–3.6 V, VI(B) = 0–VTT, and VO(B) = 0–VTT, where VTT is 0.9 V (GTL−), 1.2 V (GTL), or 1.5 V (GTL+).
Is SN74GTL2007PWR pin-compatible with other GTL translators in the same family?
No - SN74GTL2007PWR has a unique 28-pin TSSOP (PW) pinout optimized for dual-processor health signaling, including dedicated EN1/EN2 controls, open-drain I/O on pins 5A/6A/11A/7BO1/7BO2, and VREF at pin 1. It is not pin-compatible with SN74GTL16212DGGR (56-pin) or SN74GTL2003PWR (20-pin); each requires custom PCB layout per its specific signal mapping and enable structure.
