GTL2012DP,118

Translators, Level Shifters Overview

The GTL2012DP,118 is a 2-bit translating transceiver designed for interfacing 3.3 V systems with GTL-, GTL, and GTL+ buses. It operates as either a GTL-to-LVTTL sampling receiver or an LVTTL-to-GTL driver, controlled by the DIR pin. The device supports a supply voltage (VCC) range of 3.0 V to 3.6 V. It features 5 V tolerant LVTTL inputs on the A port and 3.6 V tolerant GTL I/Os on the B port. The adjustable Vref ranges from 0.5 V to 0.5VCC. Propagation delays vary between 2.8 ns and 8 ns depending on direction and termination standards.

Translators, Level Shifters Feature Summary

• Configurable bidirectional translation between LVTTL and GTL bus standards via a single direction control pin
• Input tolerance allows direct connection to 5 V CMOS or TTL logic without level shifting components
• Supports partial power-down modes to reduce system power consumption during idle states
• Robust protection against electrostatic discharge and latch-up events exceeding standard industrial limits

Translators, Level Shifters Applications

• Interfacing 3.3 V processors with legacy GTL memory buses
• System interface bridges in high-performance computing architectures
• Data routing between mixed-voltage logic domains in industrial equipment

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized NXP distributors. Confirm package integrity upon receipt, as TSSOP8 packages are sensitive to moisture. Ensure design compliance with the specified operating temperature range of -40 °C to +85 °C. Review the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions before finalizing the bill of materials.

Translators, Level Shifters Selection Notes

Select this component when bridging 3.3 V logic with GTL-family buses requiring precise voltage translation. The adjustable reference voltage allows optimization for specific GTL- variants. Consider the propagation delay specifications relative to system clock speeds. Verify that the 5 V input tolerance meets the requirements of upstream logic sources. Evaluate the thermal performance within the TSSOP8 package for the intended application environment.

Translators, Level Shifters Part Context

This part belongs to the GTL2012 family of translating transceivers manufactured by NXP Semiconductors. It is specifically packaged in the TSSOP8 plastic thin shrink small outline package, identified by the DP suffix. The device serves as a critical interface solution for maintaining signal integrity across different voltage domains in complex electronic systems.

Translators, Level Shifters Replacement Considerations

Check for the DC variant, which utilizes the VSSOP8 package, if space constraints require a smaller footprint. Verify compatibility with existing PCB footprints when substituting between TSSOP8 and VSSOP8 versions.
