Hex Inverter With Open-Drain Outputs

The SL74HC05 is identical in pinout to the LS/ALS05. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device contains six independent Gates each of which performs the Logic INVERT function. The open-drain outputs require external pull-up resistors for proper logical operation. They may be connected to other open-drain outputs to implement active-high wired-AND functions. By System Logic Semiconductor. co.
