General Description
The LCX08 contains four 2-input AND gates. The inputs
tolerate voltages up to 7V allowing the interface of 5V
systems to 3V systems.
The 74LVX08 is fabricated with advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

) or LOW-to-HIGH (t
OSLH
).
