CMOS Digital Integrated Circuits Silicon Monolithic
74HC14D
1. Functional Description
•
Hex Schmitt Inverter
2. General
The 74HC14D 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 74HC04D but the inputs have 25% V
CC
hysteresis
and with its schmitt trigger function, the 74HC14D 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:
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).
