7405: Hex Inverter (Open Collector)
All six inverters may be used independently. On any one inverter, the low-input condition drives the output to an open circuit. The high-input condition drives the output low. An output-high state can be obtained only by adding an external resistor, usually 2.2K, from output to +5 volts.
