SL74HC05 Hex Inverter with Open-Drain Outputs High-Performance Silicon-Gate CMOS 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 im
