74HC14 Hex Schmitt-Trigger Inverter
High-Performance Silicon-Gate CMOS
The 74HC14 is identical in pinout to the LS14, LS04 and the HC04. The device inputs are compatible with Standard CMOS outputs with pullup resistors, they are compatible with LSTTL outputs. The HC14 is useful to "square up" slow input rise and fall times. Due to hysteresis voltage of the Schmitt trigger, the HC14 finds applications in noisy environments.

MAXIMUM RATINGS
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
