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
