Key Features
- Quadruple 3-state bus buffer gates enabling high-impedance output control for shared bus architectures
- BCT/FBT logic family with 64mA (max I(ol)) drive strength for robust signal transmission
- SOIC-14 (R-PDSO-G14) package with unidirectional enable-low control for easy system integration
- 50pF load capacitance support suited for driving capacitive bus loads in high-speed digital designs
Applications
The SN74BCT125AD is widely used in microprocessor bus expansion, memory interfacing, and data bus isolation applications where multiple devices share a common bus. Its 3-state outputs make it ideal for backplane drivers, address/data bus buffering in embedded systems, and industrial control boards. The enable-low control and BCT logic compatibility also suit it for level shifting and signal buffering in mixed-voltage digital systems.
