SN74LV157AD

LOGIC, DATASELCT/MUX 2-1 QUAD, 16SOIC.

The SN74LV157AD is a 2-to-1 quadruple Data Selector/Multiplexer designed for 2 to 5.5V VCC operation. It contains 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 device presents true data. It 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.
