74ALVT16240DL,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVT16240DL,112 is a high-performance BiCMOS device designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V. It functions as an inverting 16-bit buffer ideal for driving bus lines. The device features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. It operates within an ambient temperature range of -40 °C to +85 °C and utilizes a 48-lead SSOP plastic shrink small outline package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features 5 V I/O compatibility allowing interface capability to systems 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.
• Provides power-up 3-state functionality and permits live insertion and extraction operations.

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
• Bus interface applications requiring inverting buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' against manufacturer documentation to confirm packaging details and reel specifications. Ensure the component matches the required SSOP48 package variant. Confirm RoHS compliance status and check for any recent product change notifications regarding manufacturing updates or obsolescence before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit inverting buffering with 3-state control. It is suitable for applications needing 5 V tolerance on inputs while operating at lower supply voltages. Consider the four independent output enable lines for granular control over bus segments. Verify that the package dimensions fit the available PCB space.
