74LCX32
Low Voltage Quad 2-Input OR Gate

with 5V Tolerant Inputs

General Description

The LCX32 con tains four 2-input O R gat es. T he i n puts tol­erate voltages up to 7V allowing the interface of 5V sys­tems to 3V systems.

The 74LCX32 is fabricated 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. Th e parametric values def ined in the Electrical Cha racteristic s tables are not guaran teed at the A bsolute Ma ximum Rating s. The “Rec om­mended Operat ing Conditions” table will define the conditions for ac t ual device operation.

Note 2: I

Absolute Maximum Rating must be observed.

Note 3: Unused inputs must be held HIGH or LOW. They may not float.
