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.
