Technical content

TOSHIBA CMOS Digital Integrated Ci rcuit Silicon Monolithic TC7MB3257FK Quad 1-of-2 Multiplexer/Demultiplexer The TC7MB3257FK is high-speed CMOS quad 1-2 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 inputs is connected to the B1 or B2 outputs determined by the combination both the select input (S) 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 are equipped with protection circuits against static discharge. Features Pin Assignment (top view)

Absolute Maximum Ratings (Note) Characteristics Symbol Rating Unit Power supply range VCC −0.5~7.0 V DC input voltage VIN −0.5~7.0 V DC switch voltage VS −0.5~7.0 V Input diode current IIK −50 mA Continuous channel current IS 128 mA Power dissipation PD 180 mW DC VCC/GND current ICC/IGND ±100 mA Storage temperature Tstg −65~150 °C Note: Exceeding any of the absolute maximum ratings, even br iefly, 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). Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 4.5~5.5 V Input voltage VIN 0~5.5 V Switch voltage VS 0~5.5 V Operating temperature Topr −40~85 °C Input rise and fall time dt/dv 0~10 ns/V Note: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
