D Enhanced Product-Change Notification
D Qualification Pedigree^†
D ESD Protection Exceeds 2000 V Per
MIL-STD-883, Method 3015; Exceeds 200 V
Using Machine Model (C = 200 pF, R = 0)
† _{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_CC
operation.
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.
