Description

The 74ALS251 is a logic implementation of a single 8-position switch with the switch position controlled by the state of three select (S0, S1, S2) inputs. True (Y) and complementary (Y) outputs are both provided.

The output enable (OE) of the 74ALS251 is active Low. When OE is High, both outputs are in High impedance state, allowing multiple connections to a common bus without driving nor loading the bus significantly.

When the outputs of the 74ALS251 more than one device are tied together, the user must ensure that there is no overlap in the active-Low portion of the output enable voltages in order to avoid high currents that could exceed the maximum current rating.
