Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance
          or even destruction.

          Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
          significant change in temperature, etc.) may cause this product to decrease in the reliability
          significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are
          within  the absolute maximum ratings and the operating ranges.

          Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
          ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. 
          reliability test report and estimated failure rate, etc).


Description

The TC7MB3253FK is high-speed CMOS dual 1-4 Multiplexer/Demultiplexer. The low on resistance of the switch allows connections to be made with minimal propagation delay time.

The TC7MB3253FK consists of two individual two-inputs multiplexer/demultiplexer with common select inputs (S1, S0). The A inputs is connected to the corresponded B1~B4 outputs determined by the combination both the select inputs (S1, S0) 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  TC7MB3253FK are equipped with protection circuits against static discharge.
