U74LVC17A
HEX SCHMITT-TRIGGER
BUFFER
DESCRIPTION
The UTC
U74LVC17A
is a high-performance, low-power,
low-voltage, Si-gate CMOS device and provides six non-inverting
buffers with Schmitt trigger action. It is capable for transforming slowly
changing 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.
