SN74LV157A 四路 2 线路到 1 线路数据选择器/多路复用器

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
