GTL2034PW,118

Overview

The GTL2034PW,118 is a 4-bit Gunning Transceiver Logic (GTL) to GTL bus buffer manufactured by NXP Semiconductors. It operates with a supply voltage (VCC) ranging from 3.0 V to 3.6 V and features inputs/outputs tolerant up to 3.6 V. The device supports GTL-, GTL, and GTL+ standards with an adjustable reference voltage (Vref) from 0.5 V to VCC / 2. Propagation delays are typically 3.1 ns for LOW-to-HIGH and 4.1 ns for HIGH-to-LOW transitions at VCC = 3.3 V. It includes ESD protection exceeding 2000 V HBM and latch-up protection over 500 mA.

Feature Summary

• Functions as a 4-bit bidirectional bus buffer compatible with GTL-, GTL, and GTL+ signaling standards.
• Provides 3.6 V tolerance on both input and output ports, enabling use in higher voltage open-drain applications.
• Supports partial power-down modes to reduce system power consumption during idle states.
• Integrates robust electrostatic discharge (ESD) protection and high latch-up immunity for reliable operation.

Applications

• High-speed data buffering in computer systems utilizing GTL logic families
• Memory interface circuits requiring signal integrity maintenance across buses
• Digital communication links between processors and peripheral devices

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP14 package variant when sourcing components. Confirm that the ambient operating temperature range of -40 °C to +85 °C aligns with your system's thermal requirements. Ensure design compatibility with the required VCC supply voltage window of 3.0 V to 3.6 V. Check for any recent product status updates or obsolescence notices directly from NXP Semiconductors before finalizing procurement plans.

Selection Notes

Select this component when interfacing between different GTL logic variants within a single voltage domain. The adjustable Vref allows optimization for specific GTL- or GTL+ noise margins. Consider the TSSOP14 package constraints regarding board space and thermal dissipation. Verify that the load capacitance requirements do not exceed the specified limits to maintain signal integrity and meet propagation delay specifications.

Part Context

This device belongs to NXP's portfolio of interface buffers designed for legacy and specialized logic families. It serves as a bridge for systems transitioning between or maintaining GTL-based architectures. The component complements other level-shifting and buffering solutions offered by the manufacturer for high-speed digital interconnects.

Replacement Considerations

The datasheet identifies GTL2034PWZ as a drop-in replacement for GTL2034PW. Both parts share identical electrical characteristics and pinouts but differ in packing methods, with the PWZ variant utilizing a Static Shielding Bag solution.

FAQ

Can the GTL2034 operate with mixed GTL standards?

Yes, the device functions as a buffer for GTL-, GTL, and GTL+ standards simultaneously, allowing interoperability between these logic families.

What is the maximum voltage tolerance for the I/O pins?

The GTL inputs and outputs are tolerant up to 3.6 V, which exceeds the standard VCC operating range.
