TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC14AP, TC74HC14AF
Hex Schmitt Inverter
The TC74HC14A is a high speed CMOS SCHMITT
INVERTER fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation. Pin
configuration and function are the same as the TC74HC04A but
the inputs have 25% V
CC
hysteresis and with its schmitt trigger
function, the TC74HC14A can be used as a line receivers which
will receive slow input signals.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40°C to 65°C. From Ta = 65°C to 85°C a derating factor of −10 mW/°C shall
be applied until 300 mW.
