SN74GTL16612ADLR

Overview

The SN74GTL16612ADLR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It facilitates voltage level translation between LVTTL and GTL/GTL+ logic families, supporting bidirectional data transfer. The device operates within a supply voltage range of 3.15 V to 5.25 V and features a typical propagation delay of 6.3 ns. Designed for surface-mount applications, it is housed in a TSSOP-56 package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports bidirectional voltage level translation between LVTTL and GTL/GTL+ standards
• Integrates 18-bit universal bus transceiver functionality for high-density data paths
• Includes reset capability to initialize the bus state

Applications

• Interfacing low-voltage TTL logic with GTL/GTL+ memory systems
• High-speed data bus translation in computer architecture
• Voltage domain bridging in embedded controller designs

Procurement Notes

Verify the specific suffix 'ADLR' against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and package variant. Ensure the design environment matches the specified 3.15 V to 5.25 V operating range. Confirm that the TSSOP-56 footprint aligns with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when interfacing LVTTL sources with GTL/GTL+ destinations requiring 18-bit parallel data handling. The device is suitable for applications needing moderate speed with a 6.3 ns propagation delay. Consider the TSSOP-56 package constraints and the specific power supply requirements of 3.15 V to 5.25 V during system design.

Part Context
