7405 Hex Inverters with Open-Collector Output IC
The 7405 Hex Inverters with Open-Collector Output IC is a standard TTL logic device that integrates six independent inverter gates within a single package. Each gate inverts its input logic level, providing a logical “NOT” function while requiring external pull-up resistors due to the open-collector transistor outputs. This device is useful in digital logic systems where signal inversion and open-collector interfacing are needed for wired-AND combinations, level shifting, or interfacing with other logic families.
Features:
- Six independent logic inverters with open-collector outputs.
- Low-power Schottky TTL technology for reduced consumption.
- Input clamp diodes for transient protection.
- Compatible with TTL input levels.
- Enables wired-OR and active-high wired-AND functions.
- Fast switching speeds for high-performance applications.
- Compact DIP-14 package for easy integration.
