Frequently Asked Questions
What is the required supply voltage range for these ICs?
HC types operate across a 2V to 6V range, while HCT types require 4.5V to 5.5V.
Is there a stable operating temperature range?
Yes, the devices maintain operation in a wide thermal range from -55°C to 125°C.
Are these components resistant to static electricity?
No, users must follow proper IC Handling Procedures because these devices are sensitive to electrostatic discharge.
Can I operate the device outside of listed ratings?
Operating above 'Absolute Maximum Ratings' is not implied and may cause permanent damage to the device.
