Overview
The GTL2034PWZ is a 4-bit GTL-/GTL/GTL+ bus buffer manufactured by NXP Semiconductors. It operates with a supply voltage (VCC) ranging from 3.0 V to 3.6 V, while inputs and outputs are tolerant up to 3.6 V. The device supports adjustable reference voltage (Vref) from 0.5 V to VCC/2. Propagation delays range from 2.8 ns to 5.2 ns depending on the GTL standard used. It features ESD protection exceeding 2000 V HBM and latch-up protection over 500 mA. The component is housed in a TSSOP14 package and operates within an ambient temperature range of -40 °C to +85 °C.
Feature Summary
- Functions as a 4-bit buffer for GTL-, GTL, and GTL+ logic standards
- Provides 3.6 V tolerance for both input and output pins
- Supports partial power-down modes to reduce consumption
- Includes robust ESD and latch-up protection mechanisms
Applications
- GTL bus buffering in server platforms
- Signal buffering for open-drain output applications
- Interface circuits requiring GTL level translation
Procurement Notes
Verify the specific ordering suffix 'Z' indicates the Static Shielding Bag (SSB) packing method rather than a functional change. Confirm the part number GTL2034PWZ matches the required TSSOP14 package and temperature range (-40 °C to +85 °C). Ensure compatibility with existing PCB footprints and soldering profiles before finalizing procurement decisions.
Selection Notes
Select this component when interfacing between different GTL variants or when higher voltage tolerance is required for open-drain configurations. The adjustable Vref allows optimization for specific GTL- GTL, or GTL+ standards. Consider the TSSOP14 package constraints and thermal requirements for the intended application environment.
Part Context
The GTL2034 is part of NXP's interface IC portfolio designed for server and data center applications. It serves as a drop-in replacement for the discontinued GTL2034PW. The device enables reliable signal transmission across GTL buses, supporting high-speed data integrity in complex electronic systems.
Replacement Considerations
The GTL2034PWZ is the confirmed public substitute for the discontinued GTL2034PW. Both parts share identical electrical specifications and pinouts.
FAQ
What is the maximum voltage tolerance for the inputs and outputs?
The GTL inputs and outputs operate up to 3.6 V.
Does the 'Z' suffix in GTL2034PWZ indicate a functional difference?
No, the 'Z' suffix denotes the use of a Static Shielding Bag (SSB) packing method; it does not change the device function.
