7405 Hex Inverter, Open Collector

The 7405 is a hex inverter integrated circuit featuring open-collector outputs. As a member of the 74-series logic family, this device contains six independent inverters that perform the logical NOT function.

Because the outputs are of the open-collector type, they require an external pull-up resistor to function in standard logic applications. This component is suitable for digital logic design, signal inversion, and interfacing tasks requiring open-collector output characteristics.
