Component qualification in accordance with JEDEC and industry  
standards to ensure reliable operation over an extended  
temperature range. This includes, but is not limited to, Highly  
Accelerated Stress Test (HAST) or biased 85/85, temperature  
cycle, autoclave or unbiased HAST, electromigration, bond  
intermetallic life, and mold compound life. Such qualification  
testing should not be viewed as justifying use of this component  
beyond specified performance and environmental limits.

description/ordering information  
The SN74LVC157A-EP quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V V  
operation.  
CC  
This device features 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 device provides true data.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator  
in a mixed 3.3-V/5-V system environment.
