U74LVC2G157
SINGLE 2-LINE TO 1-LINE
DATA SELECTOR OR
MULTIPLEXER
DESCRIPTION
The U74LVC2G157 is a single 2-line to 1-line data selector or
multiplexer which is featured a common strobe ( G ) input. When the
strobe is high, the output Y is low and Y is high regardless of the
levels of other inputs. When the strobe is low, a single bit is selected
from one of two sources and is transferred to the output with the true
and complementary data.
This device has power-down protective circuit, preventing
device destruction when it is powered down.
FEATURES
* Operate from 1.65V to 5.5V
* Inputs accept voltages to 5.5V
* Ioff supports partial-power-down mode
* Low power dissipation: ICC=10μA(Max.)
* ±24mA output drive(VCC=3.3V)
* Max tpd at 6ns of 3.3V
