4-Bit 1-of-2 Multiplexer/Demultiplexer
The TC7MBL3257C is a Low Voltage/Low Capacitance CMOS 4bit 1-of-2 Multiplexer/Demultiplexer. The low on-resistance of the switch allows connections to be made with minimal propagation delay time. This device consists of four individual two-inputs multiplexer/demultiplexer with common select input (S) and output enable ( OE ). The A input is connected to the B1 or B2 outputs as determined by the combination of both the select input (S) and output enable ( OE ). When the output enable ( OE ) input is held at “H” level, the switches are open regardless of the state of the select inputs, and a high-impedance state exists between the switches. All inputs are equipped with protection circuits against static discharge.

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).
