DM74ALS14 Hex Inverter with Schmitt Trigger Inputs
DM74ALS14
Hex Inverter with Schmitt Trigger Inputs
General Description
This device contain s six i ndepe ndent gates, each o f whi ch
performs the logic INVERT function. Each input has hysteresis which increases the noise i mmunity and tran sforms a
slowly changing input signal to a fast changin g, jitter-free
output.
Features
■ Input hysteresis
■ Low output noise generation
■ High input noise immunity
■ Switching specification at 50 pF
■ Switching specifications guaranteed over full tempera-
ture and V
CC
range
■ Advanced oxide-isolated, ion-implanted Schottky TTL
process
■ Functionally and pin-for-pin compatible with Schottky
and low power Schottky TTL counterparts
■ Improved AC performance over low power Schottky
counterpart

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
