MC74ACT257: Quad 2-Input Multiplexer with 3-State Output
For complete documentation, see the data sheet
Product Description
The MC74AC257/74ACT257 is a quad 2-input multiplexer with 3-state outputs. Four bits of data from two sources can be selected
using a Common Data Select input. The four outputs present the selected data in true (noninverted) form. The outputs may be
switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to
interface directly with bus-oriented systems.
