The 74AC257SC is a quad 2-input multiplexer with 3-STATE outputs, manufactured by On Semiconductor. This integrated circuit allows for the selection of four bits of data from two sources, controlled by a common data select input. The outputs present the selected data in a true, noninverted form.
Key electrical characteristics include an operating voltage range of 2V to 6V and output current capabilities of 24mA sourcing and sinking. The device is designed for surface mount installation in a 16-SOIC package, measuring 0.154 inches wide.
With its 3-STATE output capability, the 74AC257SC can interface directly with bus-oriented systems. The common output enable (OE) input, when HIGH, places the outputs in a high impedance state. This feature is crucial for multiplexer expansion by tying outputs together, ensuring that only one device is active at a time to avoid current issues.
The operating temperature range for the 74AC257SC is -40°C to 85°C, making it suitable for a variety of environmental conditions. Its logic implementation functions as a 4-pole, 2-position switch, where the switch position is determined by the logic levels applied to the select input.
