74HC2G14; 74HCT2G14
Dual inverting Schmitt trigger
The 74HC2G14; 74HCT2G14 is a dual inverter with Schmitt-trigger inputs. Inputs 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 V to 6.0 V
Input levels:
For 74HC2G14: CMOS level
For 74HCT2G14: TTL level
High noise immunity
CMOS low power dissipation
Balanced propagation delays
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
Specified from -40 °C to +85 °C and -40 °C to +125 °C
Applications
Wave and pulse shaper for highly noisy environments
Astable multivibrators
Monostable multivibrators
