SN74GTLPH1655DGGR

Overview

The SN74GTLPH1655DGGR is a 16-bit LVTTL-to-GTLP universal bus transceiver manufactured by Texas Instruments. It operates within an extended temperature range of -40°C to +85°C and utilizes a 64-pin TSSOP package. The device supports bidirectional data transfer with independent control capabilities. Key electrical specifications include a maximum output current (Iol) of 24 mA, a maximum supply current (ICC) of 40,000 µA, and a GTL data rate capability up to 350 Mbps. The logic family is classified as GTLP, featuring over-voltage tolerant inputs and bus-hold functionality.

Feature Summary

• Adjustable edge-rate control for optimized signal integrity
• Partial power-down mode via Ioff feature
• Over-voltage tolerant inputs compatible with 5.5 V signals
• Bus-hold circuitry to prevent floating states

Applications

• GTL data bus interfaces
• Universal bus transceivers requiring level translation
• High-speed digital communication systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change and vary by region. Ensure the component meets all environmental and export control classifications required for your specific application.

Selection Notes

Select this component when interfacing between LVTTL logic levels and GTLP buses in high-density applications. The adjustable edge rate allows designers to minimize electromagnetic interference while maintaining signal quality. Consider the 64-pin TSSOP package constraints and thermal dissipation requirements for dense PCB layouts. Verify that the input voltage tolerances align with the system's operating conditions.

Part Context

This part belongs to the Texas Instruments GTLP logic family, designed for high-performance bus applications. It serves as a bridge between different logic voltage standards, specifically converting Low Voltage Transistor-Transistor Logic to Ground Transfer Logic Plus. The device is part of a broader portfolio of universal bus transceivers aimed at simplifying system architecture in complex digital designs.

Replacement Considerations

Direct substitutes may include other 16-bit GTLP transceivers from the same family, such as the SN74GTLPH1655D. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with similar devices like the SN74GTLPH1655DL if alternative packaging is required.
