• Features back-to-back registers allowing independent control of data flow in either direction
• Supports live insertion and extraction operations through power-up 3-state behavior
• Includes robust ESD protection exceeding 2000 V under Human Body Model conditions

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus buffering applications requiring bidirectional transfer
• Temporary storage systems utilizing back-to-back register architecture
• High-speed interface circuits demanding high output drive capabilities

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' against current Nexperia or NXP documentation to confirm packaging details and availability status. Confirm that the SO24 package variant matches your PCB footprint requirements. Ensure design compliance with the specified absolute maximum ratings to prevent permanent damage during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with integrated latching is required for bidirectional data paths. The dual enable structure allows separate control over data flow directions. Consider the high output drive strength for driving heavy loads. Verify compatibility with the 4.5 V to 5.5 V supply voltage range for your system logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT series of high-performance BiCMOS logic devices. It integrates functions similar to the 74ABT245 transceiver and 74ABT373 latch into a single package.
