|
The 74ALS257 is a quad 2-input multiplexer which selects 4 bits of data from one of two sources under the control of a mon select input (S). The output enable input (OE) is active when Low. When OE is High, all of the outputs (Yn) are forced to a High impedance state (3-State) regardless of all other input conditions.
