Frequently asked questions
What is the supply voltage range of the 74HC244?
The standard 74HC family operates from 2 V to 6 V. Check the datasheet of your specific manufacturer for full limits.
How are the outputs enabled and disabled?
The two sections are controlled by active-low output enable pins 1OE and 2OE. When an enable pin is high, the corresponding outputs go to high impedance.
