74F543SCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F543SCX is an octal registered transceiver in a 24-lead SOIC package. It contains two sets of D-type latches for bidirectional data storage with separate Latch Enable and Output Enable controls. The A outputs sink 24 mA, while the B outputs sink 64 mA. Recommended operating conditions specify a supply voltage of +4.5V to +5.5V and an ambient temperature range of 0°C to +70°C. Propagation delays are typically 5.5 ns at 5.0V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Back-to-back registers provide temporary storage for data flowing in either direction.
• Separate control inputs allow independent management of inputting and outputting data flow.
• High current sinking capability supports direct driving of loads without additional buffering.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional bus architectures requiring data latching
• Memory interface circuits
• Data routing systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized channels. Confirm datasheet revision status matches design requirements. Ensure environmental compliance aligns with project specifications. Validate pinout compatibility during integration. Review absolute maximum ratings to prevent operational damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive current is required for one side of a bidirectional bus. The asymmetric output capabilities (24 mA vs 64 mA) suit applications with unequal load demands. Verify logic level compatibility with interfacing devices before implementation.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74F series of high-speed logic components. It functions as an octal registered transceiver, enabling controlled data transfer between buses. The specific SCX suffix indicates tape and reel packaging for automated assembly processes.
