– 200-V Machine Model (A115-A)

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

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) input is at a

high logic level.
