74HC14; 74HCT14
Hex inverting Schmitt trigger
Rev. 7 — 19 November 2015
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
