Product details

Overview

SN74GTL2006PWR from Texas Instruments is a 13-bit bidirectional GTL-/GTL/GTL+ to LVTTL voltage-level 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-controlled input thresholds (0.6–1.1 V), delivers ≤10 ns propagation delay (B→A), and sustains 30 mA GTL output drive at 3.3 V supply.

For engineers reviewing the SN74GTL2006PWR datasheet, SN74GTL2006PWR pinout, SN74GTL2006PWR application, or SN74GTL2006PWR equivalent, key selection criteria include GTL reference voltage tolerance (±50 mV window), open-drain I/O support on pins 5A/6A/11A, latch-up immunity (>500 mA), and −40°C to 85°C industrial temperature operation.

Technical Context

The SN74GTL2006PWR implements asymmetric bidirectional translation: LVTTL inputs (pins 2–6, 8, 10–13, 15) drive GTL outputs (pins 7, 9, 16–27), while GTL inputs (same B-port pins) drive LVTTL outputs (A-port). Translation direction is determined by signal source-not control lines-enabling passive, stateless level shifting.

VREF (pin 1) sets GTL input threshold at VREF ±50 mV and enables compatibility across GTL− (0.9 V), GTL (1.2 V), and GTL+ (1.5 V) termination standards. Dedicated open-drain I/Os (5A/6A/11A and associated B-port counterparts) support wired-OR signaling and hot-swap-safe power-down behavior with high-impedance inputs.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Supply	3.0–3.6 V - Enables direct connection to 3.3-V system rails without external regulation.
VREF Range	0.5–1.1 V - Configurable reference supporting GTL− (0.9 V), GTL (1.2 V), and GTL+ (1.5 V) bus standards.
tPLH / tPHL (B→A)	2–5.5 ns typical - Ensures sub-6 ns latency for critical health-monitoring signals like PROCHOT_L and THRMTRIP_L.
IOL (B port)	15 mA - Sustains 30-Ω series termination on GTL outputs per JEDEC GTL specification.
VIH/VIL (B port)	VREF ±50 mV - Tight input window guarantees noise margin against GTL bus ringing and crosstalk.
ESD Rating	2000-V HBM - Meets Class II requirements for handling in automated board assembly environments.
Latch-Up Immunity	>500 mA per JESD78 - Prevents destructive latch-up during GTL bus fault conditions or hot insertion.

Pinout & Package

TSSOP-28 package (PW), 4.4 mm × 9.7 mm body, 0.65 mm pitch, exposed pad not present. RoHS-compliant NiPdAu lead finish, MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1	VREF	GTL input threshold reference - must be decoupled to GND with 0.1 µF capacitor for stable switching.
2–6, 8, 10–13, 15	nAn (A-port)	LVTTL I/O - bidirectional; driven by LVTTL logic, drives LVTTL loads (16 mA sink/source).
7, 9, 16–27	nBn (B-port)	GTL-/GTL/GTL+ I/O - bidirectional; accepts GTL logic levels, drives GTL-terminated buses (15 mA sink).
14	GND	Digital ground reference - requires low-inductance connection to system ground plane.
28	VCC	3.3-V supply - bypassed with 0.1 µF ceramic capacitor near pin for transient current delivery.

Key Features

Feature	Design Value
Bidirectional GTL↔LVTTL translation	Eliminates need for separate transmit/receive translators in dual-CPU health-monitoring interconnects.
VREF-adjustable GTL input threshold	Supports seamless migration between GTL−, GTL, and GTL+ platforms using same PCB layout.
Open-drain I/O capability (5A/6A/11A)	Enables wired-OR signaling for shared interrupt lines (e.g., PROCHOT_L, THRMTRIP_L) without external pull-ups.
Power-down high-impedance inputs	LVTTL and GTL inputs float safely when VCC = 0 V - prevents backfeeding into unpowered domains.
JEDEC JESD78 latch-up immunity	Guarantees robustness in server motherboard environments where GTL bus faults may occur during thermal events.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional level translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74GTL1621DPRE	16-bit, 48-pin SSOP; higher channel count but no open-drain I/O on A-port; VREF fixed at 0.8 V.	Requires PCB redesign for pin count and footprint; lacks flexible VREF for GTL+/GTL− migration.	Choose only if 16-channel density outweighs loss of VREF adjustability and open-drain flexibility.
SN74AVC16T245DGGR	16-bit AVC translator; 1.2–3.6 V dual-supply; no GTL-specific thresholds or termination support.	Cannot replace SN74GTL2006PWR in GTL-terminated Xeon® interfaces without external resistor networks and timing validation.	Select only for generic LVTTL↔LVCMOS translation; unsuitable for JEDEC GTL-compliant designs.

Compared with SN74GTL2006PWR, SN74GTL1621DPRE offers greater channel density but sacrifices VREF configurability and open-drain I/O, while SN74AVC16T245DGGR lacks GTL-specific electrical characteristics entirely-making SN74GTL2006PWR irreplaceable for Xeon® platform health management where GTL bus compliance is mandatory.

FAQ

What is the function of VREF on SN74GTL2006PWR and how must it be configured?

VREF (pin 1) sets the input threshold voltage for all GTL-side inputs (nBn pins) to VREF ±50 mV. For GTL operation, VREF must be set to 0.8 V; for GTL+, 1.0 V; for GTL−, 0.6 V. It requires a clean, low-noise 0.1 µF ceramic bypass capacitor to GND adjacent to the pin. Incorrect VREF selection causes misreads of GTL logic states and violates JEDEC GTL specifications.

Does SN74GTL2006PWR support true bidirectional data flow without direction-control pins?

Yes. SN74GTL2006PWR performs automatic bidirectional translation: when an LVTTL signal drives an A-port pin, the corresponding B-port pin becomes an output; when a GTL signal drives a B-port pin, the corresponding A-port pin becomes an output. No external direction control is needed-behavior is inherent to the internal circuit topology and signal source.

How does SN74GTL2006PWR behave during power-down (VCC = 0 V)?

During power-down, all LVTTL and GTL inputs enter high-impedance state with no leakage to VCC. Open-drain outputs (5A/6A/11A and their B-port counterparts) also remain isolated. However, totem-pole LVTTL outputs (e.g., 1AO–4AO, 9AO) will conduct if externally pulled high while VCC = 0 V-these must be left floating or actively driven low during power-off sequences.

Can SN74GTL2006PWR replace SN74GTL2003 in existing designs?

No. SN74GTL2003 is a 6-bit translator with different pinout, fewer channels (6 vs. 13), and no open-drain I/O capability on pins 5A/6A/11A. SN74GTL2006PWR has distinct functionality for dual-CPU health monitoring-including dedicated 10AI1/10AI2 → 10BO1/10BO2 paths and 11A/11BI wired-OR support-making it non-interchangeable with SN74GTL2003 without PCB and firmware revision.

What is the maximum trace length supported by SN74GTL2006PWR on GTL buses?

SN74GTL2006PWR supports GTL bus lengths up to 100 mm with 30-Ω series termination, verified by TI's application note SPRAA70. This assumes controlled-impedance routing (60 Ω single-ended), 3.3-V VCC, 1.2-V VTT, and proper VREF decoupling. Longer traces require simulation with IBIS models or empirical validation due to increased RC delay and reflection risk.
