DESCRIPTION
The 74HC7014 is a high-speed
Si-gate CMOS device. It is specified
in compliance with JEDEC standard
no. 7A.
The 74HC7014 provides six precision
Schmitt-triggers with non-inverting
buffers. It is capable of transforming
slowly changing input signals into
sharply defined, jitter-free output
signals. The precisely defined trigger
levels are lying in a window between
0.55
×
V
CC
and 0.65
×
V
CC
. This
makes the circuit suitable to operate
in a highly noisy environment. Input
shorts are allowed to
−1.5
V and 16 V
without disturbing other channels.
