SN74LVC157A-EP数据手册TI中文资料规格书

描述 Description

The SN74LVC157A-EP quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V VCC 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.

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.
