74HC7014
Hex non-inverting precision Schmitt-trigger
Rev. 3 — 30 April 2014
Product data sheet
1. General description
The 74HC7014 is a hex buffer with precision Schmitt-trigger inputs. The precisely defined
trigger levels are lying in a window between 0.55
V
CC
and 0.65
V
CC
. It 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. Inputs include clamp diodes that enable the
use of current limiting resistors to interface inputs to voltages in excess of V
CC
. Schmitt
trigger inputs transform slowly changing input signals into sharply defined jitter-free output
signals.
2. Features and benefits
Operating voltage 3.0 V to 6.0 V
Complies with JEDEC standard no. 7A
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115A exceeds 200 V
Multiple package options
Specified from
40 C
to +85
C
and from
40 C
to +125
C
3. Applications
Wave and pulse shapers for highly noisy environments
