74ALVC38
Low Voltage Quad 2-Input NAND Gate with
Open Drain Outputs and
3.6V Tolerant Inputs and Outputs
General Description
The ALVC38 contains four 2-input NAND gates with open
drain outputs. This product is designed for low voltage
(1.4V to 3.6V) V
CC
applications with I/O compatibility up to
3.6V.
The ALVC38 is fabricated with advanced CMOS technol-
ogy to achieve high-speed operation while maintaining
CMOS low power dissipation.

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 Rat-
ings. The “Recommended Operating Conditions” table will define the condi-
tions for actual device operation.
