Description This gadget has four separate 2-input NAND gates. In positive logic, each gate executes the Boolean function Y = A B. There are balanced CMOS push-pull outputs on this chip. The word "balanced" refers to the device's ability to sink and source equivalent currents. This device's drive capabilities may result in quick edges into mild loads, hence routing and load circumstances should be examined to avoid ringing. Furthermore, the device's outputs are capable of pushing higher currents than the device can withstand without being harmed. It is critical that the device's output power be restricted to avoid overcurrent damage. At all times, the electrical and thermal limitations established in the Absolute Maximum Ratings must be observed. Push-pull CMOS outputs that are not in use should be unplugged.
