GTL2012DC,125

Translators, Level Shifters Overview

The GTL2012DC,125 is a 2-bit translating transceiver manufactured by NXP USA Inc. It facilitates interface between 3.3 V systems and GTL-/GTL/GTL+ buses. The device operates with a supply voltage (VCC) of 3.0 V to 3.6 V. It features LVTTL inputs tolerant up to 5.5 V on the A port and GTL input/output tolerance up to 3.6 V on the B port. The reference voltage (Vref) is adjustable from 0.5 V to 0.5VCC. Propagation delays range from 2.8 ns to 8 ns depending on direction and bus type.

Translators, Level Shifters Feature Summary

• Configurable as a GTL-to-LVTTL sampling receiver or an LVTTL-to-GTL driver via the DIR pin
• Provides 5 V tolerance on LVTTL inputs for direct access to TTL or 5 V CMOS signals
• Supports partial power-down mode to reduce power consumption
• Includes latch-up protection exceeding 500 mA per JESD78 standards

Translators, Level Shifters Applications

• Interface between 3.3 V logic systems and GTL-/GTL/GTL+ buses
• Connecting LVTTL devices to GTL bus architectures
• System designs requiring 5 V tolerant signal translation

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DC,125 corresponds to the VSSOP8 package variant in official NXP documentation. Confirm the product status and availability directly with NXP Semiconductors or authorized distributors, as component lifecycle status may change. Ensure the application environment meets the specified operating temperature range of -40 °C to +85 °C.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3 V LVTTL logic with GTL family buses. It is suitable for applications requiring bidirectional translation with a single direction control pin. Consider the VSSOP8 package constraints if space is limited. Verify that the system's VTT termination voltage aligns with the supported GTL-, GTL, or GTL+ specifications.

Translators, Level Shifters Part Context

The GTL2012 belongs to the GTL20xx series of translating transceivers designed for Gunning Transceiver Logic (GTL) interfaces. This series enables communication between different voltage domains, specifically bridging standard LVTTL levels with the lower voltage swings characteristic of GTL buses. The DC suffix denotes the VSSOP8 plastic very thin shrink small outline package version.

Translators, Level Shifters Replacement Considerations

Consult NXP datasheets for other members of the GTL20xx family, such as the GTL2012DP (TSSOP8 package), which shares identical electrical characteristics but differs in physical packaging. No alternative part numbers are explicitly confirmed as direct substitutes in the provided source material.
