GTL2034PW,112

Overview

The GTL2034PW,112 is a 4-bit GTL−/GTL/GTL+ bus buffer manufactured by NXP USA Inc. It operates with a supply voltage (VCC) ranging from 3.0 V to 3.6 V and features inputs and outputs tolerant up to 3.6 V. The device supports adjustable Vref from 0.5 V to VCC/2. Propagation delays vary by protocol: for GTL−, tPLH is typically 2.8 ns and tPHL is 5.2 ns; for GTL, tPLH is 3.1 ns and tPHL is 4.1 ns; for GTL+, tPLH is 3.3 ns and tPHL is 3.6 ns. It is housed in a TSSOP14 package.

Feature Summary

• Operates as a 4-bit GTL−/GTL/GTL+ to GTL−/GTL/GTL+ bus buffer
• GTL input and output pins are 3.6 V tolerant
• Supports partial power-down mode
• Includes ESD protection exceeding specified HBM, MM, and CDM standards

Applications

• Connecting GTL−/GTL/GTL+ buses in higher voltage open-drain output applications
• Buffering data lines between components operating at different GTL logic levels

Procurement Notes

Verify the specific ordering suffix '112' against current manufacturer documentation to confirm tape-and-reel packaging details, as datasheets may list generic package types. Confirm the active status of the GTL2034PW part number with NXP or authorized distributors, as legacy products may have end-of-life implications. Ensure the application environment stays within the −40 °C to +85 °C ambient temperature range specified for reliable operation.

Selection Notes

Select this component when interfacing between GTL−, GTL, and GTL+ domains requiring level translation and buffering. The 3.6 V I/O tolerance allows compatibility with slightly higher voltage nodes compared to standard 3.3 V parts. Consider the TSSOP14 package constraints for PCB layout if space is limited. Verify that the load capacitance requirements align with the dynamic characteristics provided for the target propagation delay performance.

Part Context

The GTL2034 is part of NXP's family of Gunning Transceiver Logic (GTL) buffers. It serves as a bridge for high-speed serial and parallel interfaces utilizing GTL standards. The device simplifies system design by handling voltage level shifting internally while maintaining signal integrity across the bus. It is designed for applications where multiple GTL variants must interoperate seamlessly.

FAQ

What is the function of the VREF pin?

The VREF pin sets the reference voltage for the GTL inputs and outputs. It is adjustable from 0.5 V to VCC/2 to accommodate different GTL−, GTL, and GTL+ standards.

Can the GTL2034 operate in partial power-down mode?

Yes, the device permits partial power-down, which can be useful for reducing power consumption in systems where only specific sections of the bus are active.
