SN74ABT16470DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16470DGGR is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs. The device utilizes BiCMOS technology and the ABT logic series, providing non-inverting data transfer with internal registers for latching. It supports TTL input and output levels, ensuring compatibility with standard digital systems. Key electrical characteristics include a propagation delay of 4.8 ns, a maximum power supply current of 35 mA, and an operating temperature range from -40°C to +85°C. The component is housed in a 56-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates 16-bit D-type flip-flops to register data at the A ports before transferring to B ports or vice versa.
• Provides high-drive capability with low-level output currents up to 64 mA and high-level output currents of -32 mA.
• Features three-state outputs controlled by direction and output enable inputs to manage bus traffic effectively.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data buffering and registration on system buses
• Memory-to-memory data transfers requiring signal latching
• Clocked data routing in complex digital logic circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DGGR indicates the tape-and-reel packaging format distinct from tube-packaged variants like DL. Confirm the manufacturer part number matches exactly to ensure correct logic family and pinout compatibility. Check RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity aligns with the standard reel size specified by Texas Instruments for this package type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit registered data transfer is required between different voltage domains or bus structures. The ABT technology offers faster switching speeds compared to standard ALS or AS families while maintaining similar power consumption profiles. Consider the 56-pin TSSOP footprint for PCB layout constraints. Verify that the 4.5 V to 5.5 V supply range matches your system's power rails and that the TTL-compatible inputs interface correctly with your source drivers.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ABT16470 family of 16-bit registered bus transceivers. The family shares core functional specifications but differs in packaging options such as SSOP-56 (DL) or TSSOP-56 (DGGR). All variants maintain identical electrical performance and pin configurations, allowing for flexibility in manufacturing and assembly processes without altering circuit design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74ABT16470 variants with different packaging suffixes, such as SN74ABT16470DL. Cross-family replacements like SN74ACT16470 may require verification of speed and drive strength differences. Ensure any alternative maintains the 16-bit width, registered functionality, and compatible supply voltage range.
