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 implement active-high wired-AND functions.

· Outputs Directly Interface to CMOS, NMOS, and TTL
· Operating Voltage Range: 2.0 to 6.0 V
· Low Input Current: 1.0 μA
· High Noise Immunity Characteristic of CMOS Devices
