Frequently Asked Questions

What logical function does this integrated circuit perform?

The device contains two independent gates that support the logic NAND function.

What are the key operating voltage specifications?

The recommended supply voltage range is a minimum of 4.5V and a maximum of 5.5V.

How can I order this chip in different package types?

Ceramic DIP packages use prefixes like 5420DMQB, while Molded DIP uses suffix codes such as DM7420N.

What should I do if the device might operate outside rated limits?

The 'Absolute Maximum Ratings' serve as warnings; operation beyond these limits is not guaranteed and should be avoided.
