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
