This multiplexer features both true (Y) and plement (Y) outputs as well as an Output Enable (OE) input. The OE must be at a LOW logic level to enable this device. When the OE input is HIGH, both outputs are in the high-impedance state. When enabled, address information on the data select inputs determines which data input is routed to the Y and Y outputs.
