High-Density Bus Buffering

Use the 74HC9115D/S400118 to buffer 9-bit data or address buses in microprocessor systems, providing strong drive and isolation for multiple memory or peripheral devices.

Open-Drain Level Shifting

The open-drain outputs allow level shifting from 5V logic to higher voltages (e.g., 12V) by using appropriate pull-up resistors, useful in industrial control interfaces.

Wired-OR Interrupt Controllers

Connect multiple open-drain outputs to a single interrupt line, enabling multiple devices to share one input without contention.

Driving Relay and Solenoid Coils

With external pull-ups and flyback diodes, the open-drain outputs can drive relay coils, providing logic-controlled switching in automation systems.
