74AHC3G14; 74AHCT3G14
Triple inverting Schmitt trigger
Rev. 8 — 13 May 2013
Product data sheet
1. General description
74AHC3G14 and 74AHCT3G14 are high-speed Si-gate CMOS devices. They provide
three inverting buffers with Schmitt trigger action. These devices are capable of
transforming 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.
2. Features and benefits
