KODENSHI KK74HCT14AN

TECHNICAL DATA
KK74HCT14A
Hex Schmitt-Trigger Inverter
High-Performance Silicon-Gate CMOS
The KK74HCT14A may be used as a level converter for interfacing
TTL or NMOS outputs to high-speed CMOS inputs.
The KK74HCT14A is identical in pinout to the LS/ALS14.
The KK74HCT14A is useful to “square up” slow input rise and fall
times. Due to the hysteresis voltage of the Schmitt trigger, the
KK74HCT14A finds applications in noisy environments.
• TTL/NMOS-Compatible Input Levels.
• Outputs Directly Inferface to CMOS, NMOS and TTL.
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA

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.
