74VHC14 Overview
The 74VHC14 device is an advanced high-speed CMOS hex Schmitt inverter manufactured with sub-micron silicon gate and double-layer metal wiring C2MOS technology. The internal circuit is posed of 3 stages including a buffer output, which provides high noise immunity and stable output. Power-down protection is provided on all inputs and 0 to 7 V can be accepted on inputs regardless of the supply voltage.
