Description
The CD74AC251 and CD74ACT251 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 deter-
mines which data input is routed to the Y and Y outputs.
