SN74ALVTH16827GR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16827GR is a 20-bit buffer and line driver utilizing Advanced BiCMOS Technology. It supports mixed-mode signal operation with 5-V tolerant inputs and outputs while operating on a 2.3-V to 3.6-V VCC supply. The device features two independent 10-bit sections, each with separate output-enable signals. It provides high drive capabilities of -32 mA/64 mA at 3.3 V and includes active bus-hold circuitry to prevent floating data inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages with 2.3-V to 3.6-V VCC
• Active bus-hold circuitry prevents the bus from floating without external pullup or pulldown resistors
• Power-off state disables outputs to permit live insertion and prevents driver conflict during power transitions
• Auto3-State functionality eliminates bus current loading when the output voltage exceeds VCC + 0.5 V

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory buffering in mixed-voltage systems
• Clock distribution and buffering for 2.5-V and 3.3-V architectures
• Multi-drop buses requiring TTL interface compatibility with low-voltage logic

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix against the datasheet options (DL, DGG, DGV) as the GR suffix is not explicitly listed in the provided documentation. Confirm the manufacturing status, as certain variants like the DL are marked obsolete. Ensure the orderable part number matches the required package type and temperature range for your application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 20-bit widebus buffering with 5-V tolerance. It is suitable for designs needing low static power dissipation and high drive strength at 3.3 V. Consider the separate output-enable pins for managing two distinct 10-bit sections independently. Verify thermal requirements if operating near maximum current limits.
