Hex Schmitt-Trigger Inverter
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 V

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, V
IN
and V
OUT
should be constrained to the range
GND
(V
IN
or V
OUT
)
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
).
Unused outputs must be left open.
