ORDERING INFORMATION
DESCRIPTION
The LM393 series consists of two inde
p
endent
p
recision volta
g
e com
p
arators with an offset volta
g
e
s
ecification as low as 2.0• max. for two com
p
arators which were desi
g
ned s

to o

from a sin

over a wide ran

p
eration from s
p
lit
p

pp
lies
is also
p
ossible and the low
p

current drain is inde
p
endent of the ma
g
nitude of the
p
ower

volta

These com
p
arators also have a uni
q
ue characteristic in that the in

The LM393 series was desi
g
ned to directl
y
interface with TTL and CMOS. When o
p
erated from both
p
lus and minus
p
ower su
pp
lies
,
the LM393 series will directl
y
interface with MOS lo
g
ic where their
low
p
ower drain is a distinct advanta
g
e over standard com
p
arators.
