74LVC2G38
DUAL 2-INPUT NAND GATE WITH OPEN-DRAIN OUTPUTS
Description
The 74LVC2G38 is a dual, two input NAND gate with open-drain
outputs. Both gates have open-drain outputs designed for operation
over a power supply range of 1.65V to 5.5V. The device is fully
specified for partial power down applications using I
OFF
. The I
OFF
circuitry disables the output preventing damaging current backflow
when the device is powered down. Each gate performs the positive
Boolean function

Notes:
7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device
operation should be within recommend values.
8. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
