SN74LVTH182512DGGR

Specialty Logic Overview

The SN74LVTH182512DGGR is a dual 9-bit bus transceiver from Texas Instruments, operating within the LVT logic family. It features non-inverting polarity and supports a supply voltage range of 2.7 V to 3.6 V. The device utilizes a TSSOP-64 plastic package with a maximum propagation delay of 7.7 ns at 2.7 V under 50 pF load conditions. It provides high drive capability with a maximum low-level output current of 64 mA and a maximum high-level output current of -32 mA. Designed for surface mount installation, it operates reliably across an extended temperature range from -40 °C to +85 °C.

Specialty Logic Feature Summary

• Dual 9-bit architecture enabling simultaneous bidirectional data transfer on two independent buses
• LVT logic technology ensuring compatibility with standard logic families while maintaining low power consumption
• High-drive output stage capable of driving heavy capacitive loads in demanding digital environments

Specialty Logic Applications

• High-speed data routing between microprocessors and memory subsystems
• Bidirectional level shifting between different voltage domains in system interconnects
• General-purpose bus buffering in industrial control and communication equipment

Specialty Logic Procurement Notes

Verify the specific suffix 'DGGR' corresponds to the tape-and-reel packaging variant rather than the tube version. Confirm that the ordering part number matches the exact pinout and electrical specifications required by the design. Ensure compliance with RoHS directives and check for any recent lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when a dual-channel, high-density bus interface is required within a constrained footprint. The TSSOP-64 package offers a compact solution compared to larger QFP alternatives. Consider the 7.7 ns propagation delay limit for timing-critical paths and ensure the 64 mA sink current meets the load requirements of the destination circuitry without exceeding thermal limits.

Specialty Logic Part Context

This device belongs to the SN74LVTH1825xx series of specialized bus transceivers designed for scanning test applications and general high-speed data transfer. It shares functional similarities with other members of the LVTH family but distinguishes itself through its specific 18-bit total capacity split into two 9-bit channels. The DGGR suffix indicates a reel-packaged version suitable for automated assembly processes.

Specialty Logic Replacement Considerations

The SN74LVTH182512DGG serves as the tube-packaged equivalent with identical electrical characteristics. Verify pin-to-pin compatibility if substituting packages. Cross-reference with other LVTH1825xx variants only if channel count or voltage levels differ significantly.
