SN74ALVTH16827DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16827DLR is a 20-bit buffer and line driver utilizing Advanced BiCMOS technology. It operates at 2.5-V or 3.3-V VCC but supports mixed-mode signal operation with 5-V input/output voltages. The device features two independent 10-bit sections, each with separate output-enable signals. Outputs provide high drive capability of -32 mA/64 mA at 3.3 V and -24 mA/24 mA at 2.5 V. It includes active bus-hold circuitry to prevent floating inputs and Auto3-State functionality to eliminate bus current loading when outputs exceed VCC + 0.5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by interfacing 5-V systems with 2.3-V to 3.6-V VCC environments
• Features power-off disabling of outputs to permit live insertion without driver conflict
• Incorporates active bus-hold circuitry on data inputs to maintain valid logic levels without external resistors
• Utilizes distributed VCC and GND pin configuration to minimize high-speed switching noise

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory buffering in computer systems
• Clock drivers and buffering for system buses
• Multipoint bus transmission applications
• Control signal routing in industrial control systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the 'DLR' suffix corresponds to the SSOP-56 tape-and-reel packaging variant. Ensure design-in timelines account for potential supply chain constraints associated with end-of-life products. Validate that the operating temperature range meets specific environmental requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring widebus architecture with 20-bit parallel data handling. It is suitable for applications needing TTL-compatible inputs while driving 2.5-V or 3.3-V loads. Consider the package options if space constraints require SSOP-56. Evaluate the need for bus-hold features to simplify PCB layout by removing pull-up/pull-down resistors.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVTH16827 family of 20-bit buffers/drivers. It is manufactured using Texas Instruments' Advanced BiCMOS (ABT) technology. The device is designed for 2.5-V and 3.3-V operation with 5-V tolerant I/O. It shares functional similarities with other ALVTH series devices but offers specific 20-bit width and dual 10-bit section control.
