8-Input Multiplexer, Three-State

Features

Description

• Buffered Inputs

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.

• Typical Propagation Delay
