74AC257SCX

The ON Semiconductor 74AC257SCX is a quad 2-input multiplexer featuring 3-STATE outputs. 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, non-inverted form.

Key electrical characteristics include a single supply voltage range of 2V to 6V and output currents of 24mA for both high and low states. The device operates within a temperature range of -40°C to 85°C.

Designed for surface mounting, the 74AC257SCX comes in a 16-SOIC package with specific dimensions of 0.154" (3.90mm) width. The outputs can be switched to a high impedance state by applying a logic HIGH to the Output Enable (OE) input, facilitating direct interfacing with bus-oriented systems. The common data select input (S) determines which data source is selected: LOW selects I0x inputs, and HIGH selects I1x inputs.

This multiplexer is suitable for applications requiring data selection and bus interfacing where 3-STATE outputs are beneficial. Its robust operating temperature range and standard SOIC packaging make it a versatile component for various electronic designs.
