74AHC3G14; 74AHCT3G14
Triple inverting Schmitt trigger
Rev. 9 — 4 December 2018
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.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For TSSOP8 package: above 55 °C the value of P
tot
derates linearly at 2.5 mW/K.
For VSSOP8 package: above 110 °C the value of P
tot
derates linearly at 8 mW/K.
For XSON8 package: above 118 °C the value of P
