QUADRUPLE 2-LINE TO 1-LINE
DATA
SELECTORS/MULTIPLEXERS
DESCRIPTION
The U74LVC157 is designed for 1.65V to 3.6V VCC operation.
The device features a common strobe ( G ) input. When ( G ) is
SOP-16
high, all outputs are low. When G is low, a 4-bit word is selected
from one of two sources and is routed to the four outputs.
FEATURES
* Operate From 1.65V to 3.6V
* Inputs Accept Voltages to 5.5V
* Max tpd of 5.2ns at 3.3V
* Typical VOLP (Output Ground Bounce)<0.8V at VCC=3.3V, TA=25°C
* Typical VOHV (Output VOH Undershoot)>2V at VCC=3.3V, TA=25°C
