TC74LVX14F/FT
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74LVX14F,TC74LVX14FT
Hex Schmitt Inverter
The TC74LVX14F/ FT is a high-speed CMOS HEX SCHMITT
INVERTER fabricated with silicon gate CMOS technology.
Designed for use in 3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
Pin configuration and function are the same as the TC74LVX04
but the inputs have hysteresis and with its schmitt trigger
function, the TC74LVX14 can be used as a line receivers which
will receive slow input signals.
An input protection circuit ensures that 0 to 5.5V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.

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).
