GTLP1B151K8X

Overview

The GTLP1B151K8X is a 1-bit LVTTL/GTLP transceiver manufactured by onsemi, formerly Fairchild Semiconductor. It provides signal level translation between LVTTL and GTLP logic levels with separate inputs and outputs. The device features a dedicated feedback path for diagnostics and control monitoring. It operates within a supply voltage range of 3.15V to 3.45V and supports an operating temperature range of -40°C to +85°C. The component utilizes edge rate control circuitry to minimize output noise and bus-settling time. It is housed in an 8-Lead US8 package (JEDEC MO-187, Variation CA).

Feature Summary

• Provides bidirectional interface between GTLP and LVTTL logic levels.
• Includes a separate feedback path for control and diagnostics monitoring.
• Features internal edge-rate control to reduce output noise on the GTLP port.
• Supports live insertion via power up/down and power off high impedance states.

Applications

• High-speed backplane operation requiring signal level translation.
• System control and diagnostics monitoring interfaces.
• Bidirectional data transfer between LVTTL and GTLP domains.

Procurement Notes

Verify the specific ordering suffix K8X corresponds to the 8-Lead US8 package variant as documented in the datasheet. Confirm that the component meets the required environmental specifications for the intended application. Check for any relevant product change notices or end-of-life notifications associated with this part number before finalizing procurement decisions.

Selection Notes

Select this component when interfacing systems requiring translation between LVTTL and GTLP standards. Ensure the design accommodates the specific VREF pin requirements for receiver threshold adjustment. Consider the package dimensions and pinout configuration for PCB layout optimization. Verify that the drive current capabilities meet the load requirements of the connected circuits.

Part Context

This device belongs to the GTLP1B151 family of transceivers designed for high-speed digital applications. It represents a derivative of the Gunning Transistor Logic standard, optimized for reduced output swing and improved signal integrity. The technology leverages advanced BiCMOS processes to ensure consistent performance across process, voltage, and temperature variations.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar LVTTL/GTLP translation capabilities. Verify compatibility with existing board layouts and pin configurations. Ensure that alternative components support the same operating voltage ranges and temperature specifications.
