SN74LVC1G3208
SINGLE 3-INPUT POSITIVE OR-AND GATE
SCES605A – SEPTEMBER 2004 – REVISED JUNE 2005
By tying one input to GND or V
CC
, the SN74LVC1G3208 offers two more functions. When C is tied to V
CC
, this
device performs as a 2-input OR gate (Y = A + B). When A is tied to GND, the device works as a 2-input AND
gate (Y = B ⋅ C). This device also works as a 2-input AND gate when B is tied to GND (Y = A ⋅ C).
NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the
die as the package.
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
