Texas Instruments CD74AC251 8-Input Multiplexer with 3-State Outputs CD74AC251MG4

The CD74AC251 is an 8-input multiplexer featuring three-state outputs, designed using Harris Advanced CMOS Logic technology. It provides buffered inputs and has a typical propagation delay of 6 ns at a supply voltage of 5V and a load capacitance of 50 pF. The device is equipped with both true (Y) and complement (Y) outputs, along with an Output Enable (OE) input that places the outputs in a high-impedance state when activated. This multiplexer operates within a voltage range of 1.5V to 5.5V and offers balanced noise immunity at 30% of the supply voltage. It can drive output currents of ¬±24 mA, allowing for fanout to 15 FAST,Ñ¢ ICs and the capability to drive 50Oc transmission lines. The CD74AC251 also features robust ESD protection exceeding 2kV per MIL-STD-883, method 3015, and is designed to be SCR-latchup-resistant. The device is packaged in a 16-pin SOIC format, measuring 9.9mm x 6mm.
