Additional Details

The MC74HC133N operates from a wide voltage range, typically between 2V and 6V, and is available in a 14-pin DIP package. The output of the NAND gate is low only when all thirteen inputs are high. The propagation delay is typically in the range of 8-15 ns, depending on the operating voltage. It features protection circuitry that provides overvoltage tolerance on the inputs, allowing the inputs to exceed VCC without damage or disruption. Proper decoupling capacitors should be used near the power supply pins to minimize noise and ensure stable operation.
