DM74ALS14
Hex Inverter with Schmitt Trigger Inputs
General Description
This device contains six independent gates, each of which
performs the logic INVERT function. Each input has hyster-
esis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter-free
output.
Features
s Input hysteresis
s Low output noise generation
s High input noise immunity
s Switching specification at 50 pF
s Switching specifications guaranteed over full tempera-
ture and VCC range
s Advanced oxide-isolated, ion-implanted Schottky TTL
process
s Functionally and pin-for-pin compatible with Schottky
and low power Schottky TTL counterparts
s Improved AC performance over low power Schottky
counterpart

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
