74LCX07 Low Voltage Hex Buffer with Open Drain Outputs
74LCX07
Low Voltage Hex Buffer with Open Drain Outputs
General Description
The LCX07 contains six buffers. The inputs t olerate voltages up to 7V allowing the interface of 5V syste ms to 3V
systems.
The outputs of the LCX07 ar e 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 fabricat ed with advanced CMO S technology to achieve high speed operation while maintaining
CMOS low power dissipation.

Absolute Maximum Ratings(Note 1)
Recommended Operating Conditions (Note 3)
Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The pa rametric values defined in the Elec trical Characte ristics tables are n ot guaranteed at the Absolute Ma ximum Ratings. The Recommended Operating Conditions table will define the conditions for actual device operation.
Note 2: I
O
Absolute Maximum Rating must be observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
