SL74HC05


System Logic
Semiconductor SLS

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
