Description
The 74LCX00 device is a low-voltage CMOS quad dual input NAND gate manufactured with sub-micron silicon gate and double layer metal wiring C
2
MOS technology. It is ideal for low-power and high-speed 3.3 V applications and can be interfaced to a 5 V signal environment for inputs.
It has the same speed performance at 3.3 V as the 5 V AC/ACT family, combined with lower power consumption.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.
