Description
The 74LX3G07 is a low voltage CMOS triple
buffer/driver (open drain) fabricated with sub-
micron silicon gate and double-layer metal wiring
C
2
MOS technology.
The internal circuit composed of 2 stages
including buffer output, provides high noise
immunity and stable output.
Power down protection is provided on input and 0
to 7 V can be accepted on input with no regards
to the supply voltage. This device can be used to
interface 5 to 3 V.

Maximum rating
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
