The SNx4xx00 devices are quadruple, 2-input NAND gate. A typical application of NAND gate can be as an error indicator as shown in Figure 3. If either of the sensor has an error, the error flag is high to indicate system error.
These devices use BJT technology and have unbalanced output drive with IOL and IOH specified as per the Recommended Operating Conditions.
