74LCX08 Low Voltage Quad 2-Input AND Gate with 5V Tolerant Inputs
74LCX08
Low Voltage Quad 2-Input AND Gate
with 5V Tolerant Input s
General Descript ion
The LCX08 contains four 2-input AND gates. The inputs
tolerate voltage s up to 7 V allowing th e inter face of 5V sys-
tems to 3V systems.
The 74LVX08 is fabricat ed with advanced CMO S technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.

Absolute Maximum Ratings(Note 3)
Recommended Operating Conditions (Note 5)
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 value s 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 con dit ions for ac t ual devic e operation.
Note 4: IO Absolu te Maximu m Rating must be observed.
Note 5: Unused input s m ust be he ld H I GH or LOW. They may not f l oat.
