1. General description

The 74AHC1G14 and 74AHCT1G14 are single inverters with Schmitt-trigger inputs. Inputs are

overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage

environments.

The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.

The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.

2. Features and benefits

• Wide supply voltage range from 2.0 V to 5.5 V

• Overvoltage tolerant inputs to 5.5 V

• CMOS low power dissipation

• Symmetrical output impedance

• High noise immunity

• Latch-up performance exceesds 100 mA per JESD78 Class II Level A
