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

• Wide supply voltage range from 2.0 to 6.0 V

• CMOS low power dissipation

• High noise immunity

• Unlimited input rise and fall times

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

• Complies with JEDEC standards:

• JESD8C (2.7 V to 3.6 V)

• JESD7A (2.0 V to 6.0 V)

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• Multiple package options

3. Applications

• Wave and pulse shapers

• Astable multivibrators

• Monostable multivibrators
