Product details

Overview

SN74GTL2007PW from Texas Instruments is a 12-bit bidirectional GTL-/GTL/GTL+ to LVTTL voltage-level translator in a 28-pin TSSOP package, featuring dual enable controls (EN1/EN2), open-drain I/O (11A/11BO), and integrated series termination on TTL outputs (30 Ω). It operates from 3.0 V to 3.6 V supply, supports VREF-adjustable GTL reference (0.6–1.1 V), and targets dual-processor platform health management interfaces.

For engineers reviewing the SN74GTL2007PW datasheet, SN74GTL2007PW pinout, SN74GTL2007PW application, or SN74GTL2007PW equivalent, key selection criteria include bidirectional translation capability between GTL-family and 3.3-V LVTTL logic, controlled enable timing with glitch suppression on 7BO1/7BO2, open-drain compatibility for wired-OR signaling, and JEDEC JESD78 latch-up compliance for robust system integration.

Technical Context

The SN74GTL2007PW implements asymmetric bidirectional translation: LVTTL-side inputs drive GTL outputs via active pull-down with external VTT termination, while GTL-side inputs (referenced to VREF) drive LVTTL outputs using totem-pole or open-drain configurations. It includes two independent enable paths-EN1 controls 1AO–4AO and EN2 controls 5A–6A/7BO1–7BO2-with internal delay on EN2 to prevent transient glitches during 5BI/6BI-to-5A/6A transitions.

Its architecture supports mixed-mode operation: pins 11A/11BO operate as open-drain I/O pairs compatible with 1.2-V GTL−, 1.2-V GTL, or 1.5-V GTL+ standards; pins 9BI/9AO provide dedicated unidirectional GTL→LVTTL translation; and pins 10AI1/10AI2 feed a 2-input NAND gate driving 10BO1/10BO2. All B-port inputs are referenced to VREF ±50 mV thresholds, ensuring noise margin across GTL variants.

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 30-Ω termination on LVTTL outputs.	Targets wider bus interfaces (e.g., address/data multiplexing); lacks EN2 glitch suppression for FORCEPR_L.	Choose when scaling beyond 12 bits or requiring separate termination control; avoid if sub-10 ns thermal alert latency is required.
SN74AVC16T245DGGR	16-bit AVC-series translator, 1.2–3.6 V supply range, no VREF pin, fixed LVTTL thresholds.	Designed for general-purpose voltage translation (e.g., 1.8 V ↔ 3.3 V); incompatible with GTL family VREF-referenced inputs.	Use only for non-GTL applications; cannot replace SN74GTL2007PW in Xeon platform health management due to missing VREF and GTL-specific timing.

Compared with SN74GTL16212DGGR and SN74AVC16T245DGGR, the SN74GTL2007PW uniquely combines GTL-family VREF configurability, EN2 glitch suppression, and integrated 30-Ω LVTTL termination-making it irreplaceable for time-critical dual-CPU thermal and error signaling where GTL protocol compliance is mandatory.

FAQ

What is the function of the VREF pin on the SN74GTL2007PW?

The VREF pin on the SN74GTL2007PW sets the input threshold voltage for all GTL-side (B-port) inputs (pins 7,9,16–22,24–27). It must be externally biased to 0.6 V for GTL−, 0.8 V for GTL, or 1.0 V for GTL+ operation. This reference directly determines the LOW/HIGH decision point for GTL signals, enabling compatibility across GTL voltage variants while maintaining noise immunity per JEDEC specifications. The SN74GTL2007PW does not generate VREF internally.

Does the SN74GTL2007PW support powered-down high-impedance behavior on all I/O pins?

Yes-the SN74GTL2007PW exhibits high-impedance behavior on all LVTTL inputs (including 10AI1/10AI2) when VCC = 0 V, preventing leakage to the 3.3-V rail. GTL inputs and open-drain outputs (11A/11BO, 7BO1/7BO2) also remain isolated under power-down conditions. However, totem-pole LVTTL outputs (1AO–4AO, 9AO) do not actively drive but present high impedance with no current flow when pulled high during VCC = 0 V, as confirmed in TI's application notes.

How does the EN2 enable path differ from EN1 in the SN74GTL2007PW?

The EN2 enable path (pin 23) controls outputs 5A, 6A, 7BO1, and 7BO2 and incorporates an internal delay to prevent low-glitch generation during transient conditions-specifically when 5BI/6BI transitions from LOW to HIGH and the corresponding 5A/6A outputs lag by up to 100 ns. EN1 (pins 2–6,8,10–13,15) enables 1AO–4AO without such delay. This distinction makes EN2 essential for glitch-sensitive signals like FORCEPR_L in dual-CPU power coordination, whereas EN1 serves standard data translation.

Can the SN74GTL2007PW translate between GTL+ and LVTTL without external components?

Yes-the SN74GTL2007PW supports GTL+ (1.5 V) to LVTTL translation without external biasing components when VREF is set to 1.0 V and VTT is supplied at 1.5 V. Its B-port inputs accept GTL+ logic levels referenced to VREF, and its LVTTL outputs swing rail-to-rail (0 V to VCC) with 16-mA drive strength. The integrated 30-Ω series termination on LVTTL outputs further eliminates need for discrete resistors, enabling direct connection to 3.3-V LVTTL receivers in Xeon platform designs.

What JEDEC standards does the SN74GTL2007PW comply with for reliability testing?

The SN74GTL2007PW complies with JEDEC JESD78 for latch-up immunity (Class II) and JESD22 for ESD robustness: 2000-V Human-Body Model (HBM), 200-V Machine Model (MM), and 1000-V Charged-Device Model (CDM). These qualifications ensure survivability during board assembly, handling, and field operation in server-class environments where electrostatic discharge and latch-up events pose significant reliability risks. Compliance is verified per TI's production test flow and documented in the SCLS609 datasheet.
