SN74ALVTH162827VR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH162827VR is a 20-bit buffer and line driver manufactured by Texas Instruments, utilizing Advanced BiCMOS (ABT) technology. It operates at supply voltages of 2.5 V or 3.3 V with inputs capable of interfacing with 5-V systems. The device features two independent 10-bit sections, each with separate output-enable signals. Outputs are designed to sink up to 12 mA and include equivalent 30-Ω series resistors. It provides high-impedance states during power-up and power-down to prevent driver conflict.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by providing TTL interface compatibility for 5-V input and output voltages while operating on lower supply rails.
• Incorporates active bus-hold circuitry on data inputs to maintain valid logic levels without requiring external pullup or pulldown resistors.
• Features Auto3-State functionality that eliminates bus current loading when the output voltage exceeds the supply voltage plus 0.5 V.
• Utilizes a flow-through architecture and distributed VCC/GND pin configuration to facilitate printed circuit board layout and minimize switching noise.

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory buffering in computer systems
• Clock distribution and buffering
• Cache memory drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized channels as this part number may be obsolete. Confirm package integrity upon receipt, as the TVSOP-56 housing is sensitive to mechanical stress. Ensure design compliance with absolute maximum ratings, particularly regarding input voltage limits and thermal impedance, to maintain long-term reliability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring widebus 20-bit buffering with mixed-voltage capabilities. It is suitable for applications needing low static power dissipation and robust ESD protection exceeding 2000 V per MIL-STD-883. Consider the TVSOP-56 package constraints for PCB layout and ensure adequate thermal management within the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74ALVTH162827 family, which includes variants such as the SN74ALVTH162827DL and SN74ALVTH162827GR. These parts share identical electrical characteristics and logical functions but differ in packaging options, including SSOP, TSSOP, and TVSOP configurations. The VR suffix specifically denotes the Thin Very Small-Outline (DGV) package type.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other SN74ALVTH162827 variants like the SN74ALVTH162827DL or SN74ALVTH162827GR, provided the package footprint is compatible. Verify that any substitute maintains the same ABT technology characteristics and 56-pin TVSOP dimensions if physical interchangeability is required.
