74ALVT16240DGG,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVT16240DGG,118 is a high-performance BiCMOS inverting 16-bit buffer designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V. It features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. The device supports live insertion and extraction, offers power-up 3-state functionality, and includes bus hold data inputs to eliminate external pull-up resistors. Propagation delays range from 0.5 ns to 3.7 ns depending on supply voltage and load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features 5 V I/O compatibility allowing interface with systems operating at 5 V supply without bus current loading when outputs are tied to a 5 V bus.
• Includes bus hold data inputs that eliminate the need for external pull-up resistors to hold unused inputs in a defined state.
• Provides power-up 3-state capability ensuring outputs remain in a high-impedance state during power transitions.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in high-speed digital systems
• Interface between 2.5 V/3.3 V logic and 5 V systems
• Applications requiring live insertion and extraction

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component manufacturer origin, as datasheets reference Philips Semiconductors while ordering suffixes may indicate Nexperia. Confirm the package type matches the required SOT362-1 TSSOP48 specification. Ensure the temperature range aligns with the -40 °C to +85 °C operational limits specified in the product documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit inverting buffering with 3-state outputs. It is suitable for applications needing 5 V tolerance on inputs and outputs while operating at lower supply voltages. Consider the propagation delay specifications relative to system clock speeds and ensure adequate thermal management within the recommended operating temperature range.
