GTL2005PW/G-T

Translators, Level Shifters Overview

The GTL2005PW/G-T is a quad translating transceiver designed for interfacing 3.3 V systems with GTL/GTL+ buses. It operates as either a GTL-to-TTL sampling receiver or a TTL-to-GTL interface, controlled by the DIR pin. The device supports live insertion and extraction while maintaining latch-up protection exceeding 500 mA per JESD78. It features ESD protection exceeding 2000 V HBM and 1000 V CDM. The LVTTL interface is tolerant up to 5.5 V, allowing direct access to TTL or 5 V CMOS outputs. The component is housed in a TSSOP14 package.

Translators, Level Shifters Feature Summary

• Quad bidirectional bus interface supporting GTL/GTL+ and LVTTL/TTL levels
• Configurable direction control via DIR pin for sampling reception or driving
• Supports live insertion and extraction without system disruption
• High robustness with latch-up protection and extensive ESD tolerance

Translators, Level Shifters Applications

• Interfacing 3.3 V logic systems with GTL/GTL+ buses
• Connecting TTL or 5 V CMOS outputs to low-voltage logic domains
• Systems requiring hot-plug capability for bus connections

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct package orientation and tape-and-reel specifications. Confirm that the GTL reference voltage (Vref) requirements align with the target GTL- standard implementation. Ensure unused inputs are tied to defined logic levels to prevent floating states during operation.

Translators, Level Shifters Selection Notes

Select this component when bridging 3.3 V systems with GTL/GTL+ buses is required. It is suitable for applications needing bidirectional translation between LVTTL/TTL and GTL domains. Consider the Vref linearity degradation below 0.8 V; if lower reference voltages are necessary, evaluate alternative devices like the GTL2014 for improved noise margins.

Translators, Level Shifters Part Context

The GTL2005 belongs to NXP's family of Gunning Transceiver Logic (GTL) interface solutions. It complements other translators like the GTL2014, which offers different propagation delay characteristics. This device specifically addresses the need for non-latched translation between 3.3 V LVTTL/TTL and various GTL standards, facilitating integration in mixed-voltage digital environments.

Translators, Level Shifters Replacement Considerations

The datasheet identifies the GTL2014 as an alternative within the same product positioning diagram, particularly for applications where different propagation delay characteristics are preferred over the GTL2005.
