SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
J SUFFIX  
CERAMIC PACKAGE  
CASE 632–08  
The MC54/74HCT14A may be used as a level converter for interfacing  
TTL or NMOS outputs to high–speed CMOS inputs.  
The HCT14A is identical in pinout to the LS14.

The HCT14A is useful to “square up” slow input rise and fall times. Due to  
the hysteresis voltage of the Schmitt trigger, the HCT14A finds applications  
in noisy environments.
