Description

 The TC7MB3251FK is high-speed CMOS 1-8  multiplexer/demultiplexer. The low on resistance of the switch  allows connections to be made with minimal propagation delay  time.

The TC7MB3251FK  is 1 to 8 multiplexer/demultiplexer controlled by  the combination of select inputs (S0, S1, S2) and output enable  (OE). The A inputs is connected to the corresponded B1~B8  outputs determined by the combination both the select inputs (S0,S1, S2) and output enable (OE). When the output enable (OE))  input is held "H" level, the switches are open with regardless the  state of select inputs and a high-impedance state exists between  the switches.

All inputs of TC7MB3251FK are equipped with protection circuits against static  discharge.
