资 源 简 介

The ’V157A devices are quadruple 2-line to 1-line data selectors/mulTIplexers designed for 2-V to 5.5-V VCC operaTIon. These devices contain inverters and drivers to supply full data selecTIon to the four output gates. A separate strobe (G) input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The ’LV157A devices present true data. These devices are fully specified for parTIal-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
