Product data sheet
1. General description
The 74HC14; 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features
reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include
clamp diodes, this enables the use of current limiting resistors to interface inputs to
voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals
into sharply defined jitter-free output signals.
2. Features and benefits
Complies with JEDEC standard no. 7A
Low-power dissipation
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
3. Applications
Wave and pulse shapers
Astable multivibrators
Monostable multivibrators
