74AHC1G17; 74AHCT1G17
Single Schmitt trigger buffer
Rev. 2 — 5 October 2016
Product data sheet
1. General description
The 74AHC1G17 and 74AHCT1G17 are single buffers 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
