74AHC14; 74AHCT14
Hex inverting Schmitt trigger
The 74AHC14; 74AHCT14 is a hex inverter with Schmitt-trigger inputs. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
Balanced propagation delays
Input levels:
For 74AHC14: CMOS level
For 74AHCT14: TTL level
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
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
