74HC14; 74HCT14
Hex inverting Schmitt trigger
Rev. 8 — 22 May 2020
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

(1) This is not a ground pin. There is no electrical or
mechanical requirement to solder the pad. In case
soldered, the solder land should remain floating or
connected to GND.
