The CD74AC251 8-input multiplexers that utilize the Harris Advanced CMOS Logic technology. This multiplexer features both true (Y) and complement (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.
