DESCRIPTION The 74LVC08A is a low voltage CMOS QUAD 2-INPUT AND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for 1.65 to 3.6 VCC
operations and low power and low noise applications. It can be interfaced to 5V signal environment for inputs in mixed 3.3/5V system. It has more speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
