74ACT258 - Quad 2-Input Multiplexer

General Description

The ACT258 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 the complement (inverted) form.

74ACT258 Quad 2-Input Multiplexer with 3-STATE Outputs November 1988 Revised November 1999 74ACT258 Quad 2-Input Multiplexer with 3-STATE Outputs General Description The ACT258 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 the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
