74LCX38
Low Voltage Quad 2-Input NAND Gate (Open Drain)
with 5V Tolerant Inputs
General Description
The LCX38 contains four 2-input open drain NAND gates.
The inputs tolerate voltages up to 7V allowing the interface
of 5V systems to 3V systems.
The 74LCX38 is fabricated with advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs
s 2.3V–3.6V VCC specifications provided
s 6.5 ns tPD max (VCC = 3.3V), 10 µA ICC max
s Power down high impedance inputs and outputs
s ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 150V

Note 1: The Absolute Maximum Ratings are those beyond which the safety of the device cannot be guaranteed. The device should not be operating at these
limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recommended
Operating Conditions” table will define the conditions for actual device operation.
Note 2: IO Absolute Maximum Rating must be observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
