Product Summary
The TC74HC4072AF is a high speed CMOS 4-input OR gate fabricated with silicon gate C2MOS technology. The TC74HC4072AF achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 4 stages including buffered outputs, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
