74LCX11 Low Voltage Triple 3-Input AND Gate with 5V Tolerant Inputs

April 1995
Revised July 2005

General Description

The LCX11 is a triple 3-input AND gate with buffered out­puts. LCX devices are des igned for low voltage (2.5V or

3.3V) operation with the added capability of interfacing to a
5V signal environment.

The 74LCX11 is fabricated with a dvanced CMOS technol­ogy to achieve high speed operation while maintaining
CMOS low power dissipation.

Note 3: 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 para metric va lues defined in the Elec trical Cha racteristic s tables are n ot guarantee d at the A bsolute Ma ximum R atings . The “Recom-
mended Operating Conditions” table will define the conditions for act ual device operation.
