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.
- 2-V to 5.5-V VCC Operation
