74HC14; 74HCT14
Hex inverting Schmitt trigger
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.
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: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
Applications
Wave and pulse shapers
Astable multivibrators
Monostable multivibrators
