TECHNICAL DATA
KK74HC05A Hex Inverter with Open-Drain Outputs
The KK74HC05A 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/ALS TTL outputs. This device contains six independent gates, each of which performs the logic INVERT function. The open-drain outputs require external pullup 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.
