74ABT543ADB,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT543ADB,112 is an octal registered transceiver manufactured by NXP Semiconductors. It integrates BiCMOS technology to provide high-speed operation with low power dissipation and strong output drive capabilities. The device features two sets of D-type latches for temporary data storage in either direction. It supports a supply voltage range of 4.5 V to 5.5 V and operates within an ambient temperature range of -40 °C to +85 °C. The component utilizes a 24-lead SSOP plastic shrink small outline package (SOT340-1) with a body width of 5.3 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Back-to-back registers for storage
• Separate controls for data flow in each direction
• Live insertion and extraction permitted

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus applications requiring bidirectional transfer
• Memory buffer interfaces
• I/O port expansion systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the manufacturer designation aligns with current Nexperia or NXP product lines, as business structures have evolved. Ensure the SSOP24 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous bidirectional data buffering with independent latch control. The dual enable inputs allow flexible configuration for both transparent and latched modes. Consider the high output drive capability for driving heavy loads or multiple downstream devices without additional buffering stages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, known for high performance and compatibility with standard TTL levels. The 'ADB' suffix specifically denotes the SSOP24 package variant, distinguishing it from SO24 or TSSOP24 versions. It serves as a registered transceiver solution for high-speed digital signal routing in industrial and computing environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for 74ABT543AD or 74ABT543APW if different packaging is acceptable. Verify functional equivalence with other octal latched transceivers from the same logic family.
