Frequently Asked Questions
What is the operating voltage range for this device?
The recommended operating supply voltage (VCC) is between 2 V and 6 V.
How can I use this NAND gate with high noise immunity?
You can use it against static discharge and transient excess voltage by connecting an external pull-up resistor.
What is the average power dissipation formula?
The current (I) is calculated using: I = C x V x f + I/4 per gate, where C is capacitance, V is voltage, and f is frequency.
Are these components suitable for critical life support systems?
No, STMicroelectronics products are not authorized for use as critical components in life support devices or systems without express written approval.
