MC74AC257 - QUAD 2-INPUT MULTIPLEXER
The MC74AC257/74ACT257 is a quad 2 *input multiplexer with 3 *state outputs.
It selects four bits of data from two sources under control of a Common Data Select input.
When the Select input is LOW, the I0x inputs are selected and when Select is HIGH, the I1x inputs are selected.

Quad 2-Input Multiplexer with 3-State Outputs MC74AC257, MC74ACT257 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 oriente
