DESCRIPTION
The 74HC3G/HCT3G14 is a high-speed Si-gate CMOS
device.
The 74HC3G/HCT3G14 provides three inverting buffers
with Schmitt-trigger action. This device is capable of
transforming slowly changing input signals into sharply
defined, jitter-free output signals.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referenced to GND (ground = 0 V).
Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Above 110
C the value of P
D
derates linearly with 8 mW/K.
