SN74HSTL16918DGGR

Latches Overview

The SN74HSTL16918DGGR is a 9-bit to 18-bit HSTL-to-LVTTL memory address latch manufactured by Texas Instruments. It belongs to the HSTL technology family and operates within an industrial temperature range of -40°C to 85°C. The device is housed in a 48-pin TSSOP package group. It functions as a catalog-rated component designed for memory address latching applications, converting High-Speed Transceiver Logic levels to Low Voltage Transistor-Transistor Logic.

Latches Feature Summary

• Converts HSTL input signals to LVTTL output levels for memory addressing
• Supports 9-bit to 18-bit data width configurations
• Operates reliably across the full industrial temperature range

Latches Applications

• Memory address latching in computer systems
• Data bus interface circuits requiring level translation
• High-speed digital logic interfaces

Latches Procurement Notes

Verify the specific suffix DGGR confirms the 48-TSSOP package and tape-and-reel packaging format. Confirm the operating temperature range matches the -40°C to 85°C specification required for your design environment. Ensure compatibility with HSTL Class I or II standards if applicable to your system architecture.

Latches Selection Notes

Select this component when HSTL-to-LVTTL level translation is required for memory address buses. The 48-pin TSSOP package suits surface-mount designs with space constraints. Verify that the 9-to-18-bit latch functionality aligns with the target memory controller interface requirements.

Latches Part Context

This part is part of the 74HSTL series, which provides high-speed logic solutions compatible with SDRAM and other synchronous memory technologies. The SN74HSTL16918 specifically addresses the need for translating between different logic voltage standards in complex digital systems.

Latches Replacement Considerations

The 74HSTL16918DGGRG4 is a verified equivalent part number offering identical functionality and specifications.
