74ACT125SCX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT125SCX is a quad buffer with 3-state outputs belonging to the ACT logic series. It operates on a single supply voltage ranging from 4.5V to 5.5V, typically 5V. The device features four independent buffers, each with a separate output enable control. Outputs are high-drive capable, providing 24mA source and sink current. Propagation delay is specified at 10ns under standard test conditions of 5V supply and 50pF load capacitance. The component is housed in a 16-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel provides traceability documentation. Confirm RoHS compliance status as historical Fairchild parts may vary. Validate that the supplier sources directly from authorized distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5V logic systems requiring high drive strength and three-state bus isolation. Compare propagation delays against system timing requirements. Consider package availability and thermal performance for PCB layout. Verify input voltage levels match the driving source to ensure proper logic threshold recognition.
