SN74GTL16612DLR

Overview

The SN74GTL16612DLR is an 18-bit universal bus transceiver manufactured by Texas Instruments, designed for voltage level translation between LVTTL and GTL/GTL+ logic families. It operates within a supply voltage range of 3.15 V to 5.25 V and features a propagation delay of 6.3 ns. The device supports bidirectional data transfer across 18 channels and is housed in a TSSOP-56 surface-mount package. It functions reliably within an industrial temperature range of -40°C to +85°C, providing robust interface capabilities for high-speed digital systems requiring mixed-voltage compatibility.

Feature Summary

• Provides universal bidirectional bus transceiving between LVTTL and GTL/GTL+ logic levels
• Integrates 18 independent channels for high-density data path management
• Supports system reset functionality for controlled initialization states

Applications

• Backplane interconnects in telecommunications infrastructure
• Voltage translation interfaces in computer memory subsystems
• Data routing in industrial control network architectures

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging configuration when sourcing components. Confirm that the operating voltage requirements align with the target system's power rails, as the device supports a wide range from 3.15 V to 5.25 V. Ensure thermal management strategies account for the specified industrial temperature limits during operation.

Selection Notes

Select this component when interfacing between low-voltage TTL-compatible logic and grounded termination logic standards. Consider the 18-bit width for applications requiring parallel data handling without multiple cascaded devices. Evaluate the TSSOP-56 footprint against available PCB real estate constraints before finalizing the design.

Part Context

This part belongs to the SN74GTL16612 series of voltage translators. It serves as a bridge between different logic families, enabling communication between components operating at distinct voltage levels. The series is engineered for high-speed data transmission in environments where signal integrity and voltage compatibility are critical for system stability.

Replacement Considerations

Direct substitutes may include other 18-bit GTL/LVTTL translators from the same manufacturer family. Verify pinout compatibility and electrical specifications before swapping. Alternative packages such as SSOP-56 may require mechanical adaptation.
