Hex Schmitt-Trigger Inverter
ORDERING INFORMATION
KK74LV14N Plastic
KK74LV14D SOIC
TA = -40° to 125° C for all packages
The 74LV14 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT14.
The 74LV14 provides six inverting buffers with Schmitt-trigger action.
• Wide Operating Voltage: 1.0 to 5.5 V
• Optimized for Low Voltage applications: 1.0 to 3.6 V
• Accepts TTL input levels between VCC =2.7 V and VCC =3.6 V
• Low input current

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≤(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 left open.
