Description

These quadruple 2-line to 1-line data selectors/multiplexers LVC257A are designed for 1.65-V to 3.6-V VCC operation.

The 'LVC257A devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (OE</a>) input is at a high logic level.
