General Description
The LCX07 contains six buffers. The inputs tolerate volt-
ages up to 7V allowing the interface of 5V systems to 3V
systems.
The outputs of the LCX07 are open drain and can be
connected to other open drain outputs to implement
active HIGH wire AND or active LOW wire OR functions.
The 74LCX07 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.
