About this manual

The STMicroelectronics 74LCX14 is a low voltage CMOS hex Schmitt inverter fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is designed for low power and high speed 3.3V applications while maintaining compatibility with 5V signal environments for inputs.

The device features symmetrical output impedance, power down protection on inputs and outputs, and guaranteed PCI bus levels. It offers balanced propagation delays and a hysteresis voltage typically of 0.8V, making it suitable for line receivers with slow rise/fall input signals. The package mechanical data includes SO-14 and TSSOP14 options.
