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

•

ESD protection:

•

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V

•

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

Multiple package options

Specified from -40 °C to +85 °C and from -40 °C to +125 °C
