SN74GTL16612ADL

Overview

The SN74GTL16612ADL is an 18-bit universal bus transceiver manufactured by Texas Instruments. It facilitates voltage level translation between LVTTL and GTL/GTL+ signaling standards, supporting bidirectional data transfer with a reset function. The device operates within a supply voltage range of 3.15 V to 5.25 V and features a maximum propagation delay of 6.3 ns. Designed for surface-mount applications, it is housed in a TSSOP-56 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports bidirectional voltage level translation between LVTTL and GTL/GTL+ logic families
• Includes a dedicated reset function for bus initialization
• Provides 18-bit wide data path capability for high-bandwidth interfaces

Applications

• Backplane interconnect systems requiring GTL/GTL+ to LVTTL conversion
• High-speed memory interface circuits
• Universal bus transceivers in server and storage architectures

Procurement Notes

Verify the specific suffix 'ADL' against the manufacturer's official ordering guide to confirm the exact package type (TSSOP-56) and commercial grade temperature rating. Ensure compatibility with system power supplies within the 3.15 V to 5.25 V range. Confirm that the required signal integrity meets the 6.3 ns propagation delay specification for the target application timing constraints.

Selection Notes

Select this component when interfacing LVTTL controllers with GTL or GTLP memory subsystems. The 18-bit width reduces component count compared to narrower transceivers. Verify that the TSSOP-56 footprint fits the PCB layout and that the thermal performance is adequate for the expected ambient conditions within the specified industrial temperature range.

Part Context

This device belongs to the SN74GTL16612 series of universal bus transceivers. It is part of Texas Instruments' portfolio of GTL-compatible logic solutions designed for high-performance computing environments. The series provides standardized voltage translation capabilities essential for mixing different logic families in complex digital systems.

Replacement Considerations

Public documentation references the SN74GTL16612DGGR as a variant within the same functional family, differing primarily in packaging and reel specifications. Cross-reference the specific suffix requirements with the manufacturer's current replacement matrix before substitution.
