74HC257 is a 16 Pin Quad 2-input multiplexer IC with 3-state outputs, designed to handle signals from 4-bit data sources to 4-output data lines in bus-organized systems. It operates at a voltage range of 2V to 6V, with a maximum low input current of 1uA and a low power consumption of 80uA max. The 3-state outputs ensure that the data lines are not loaded when the OE (G\) input is at a high logic level. For proper functionality, G\ should be connected to VCC through a pull-up resistor during power up or power down, with the resistor value determined by the driver's current-sinking capability.
