74LCX10
Low Voltage Triple 3-Input NAND Gate
with 5V Tolerant Inputs
General Description
The LCX10 contains three 3-input NAND gates. The inputs
tolerate voltages up to 7V allowing the interface of 5V sys-
tems to 3V systems.
The 74LCX10 is fabricated with advanced CMOS technol-
ogy 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 parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The "Recom-
mended 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.

AC Electrical Characteristics
Note 4: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
).
