www.DataSheet4U.com MOTOROLA SEMICONDUCTOR TECHNICAL DATA Hex Schmitt-Trigger Inverter High–Performance Silicon–Gate CMOS The MC54/74HC14A 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 HC14A is useful to “square up” slow input rise and fall times. Due to hysteresis voltage of the Schmitt trigger, the HC14A finds applications in noisy environments. MC54/74HC.

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 (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be.
