LC257A - Texas Instruments

LC257A Quadruple 2-Line to 1-Line Data Selectors/Multiplexers

These quadruple 2-line to 1-line data selectors and multiplexers are designed for 1.65-V to 3.6-V VCC operation. The SNx4LVC257A 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) input is at a high logic level. Inputs ca.
