DESCRIPTION/ORDERING INFORMATION
These quadruple 2-line to 1-line data selectors/multiplexers are designed for 1.65-V to 3.6-V VCC operation.
The 'LVC157A devices feature a common strobe (G) input. When G is 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. The devices provide true data.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
The value of VCC is provided in the recommended operating conditions table.
The package thermal impedance is calculated in accordance with JESD 51-7.
The package thermal impedance is calculated in accordance with JESD 51-5.
For the D package, above 70°C the value of Ptot derates linearly with 8 mW/K.
For the DB, NS, and PW packages, above 60°C the value of Ptot derates linearly with 5.5 mW/K.
