74AHC1G14-Q100;
74AHCT1G14-Q100
Inverting Schmitt trigger
Rev. 1 — 13 July 2012
Product data sheet
1. General description
74AHC1G14-Q100 and 74AHCT1G14-Q100 are high-speed Si-gate CMOS devices.
They provide an inverting buffer function with Schmitt-trigger action. These devices can
transform slowly changing input signals into sharply defined, jitter-free output signals.
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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
