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
