The UTC U74LVC2G17 is a high-performance, low-power,
low-voltage, Si-gate CMOS device which provides two independent
buffers with Schmitt trigger action. It is capable of transforming
slowly changed input signals into sharply defined, jitter-free output
signals.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input negative-voltage and output voltage ratings may be exceeded if the input and output current
ratings are observed.
3. The value of VCC is provided in the recommended operating conditions table.
