SN74LS05 IC Hex Inverter Digital Microscope Selectable Power On timer =The SN74LS05 device contains six independent inverters. To perform correctly, the open collector outputs require pullupresistors. These devices (SN54LS05, SN54S05, SN7405, SN74LS05, SN74S05) (hex inverters) may be connected to other open collector outputs to implement active low wired OR or active high wired AND functions. Open collector devices often are used to generate high VOH levels. Features: Hex Inverter with Open collector Output Contains six
