SN54LVC257A 的說明
These quadruple 2-line to 1-line data selectors and multiplexers are designed for 1.65V to 3.6V 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 can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V or 5V system environment.
