TC7MB3253FT/FK
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TC7MB3253FT, TC7MB3253FK
Dual 1-of-4 FET Multiplexer/Demultiplexer
The TC7MB3253 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. This device consists of two individual two-inputs multiplexer/demultiplexer with common select inputs (S1, S0). The A inputs is connected to the corresponded B1 to 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 are equipped with protection circuits against static discharge.

Absolute Maximum Ratings (Note)
Characteristics Power supply range DC input voltage DC switch voltage Input diode current Continuous channel current Power dissipation DC VCC/GND current Storage temperature Symbol VCC VIN VS IIK IS PD ICC/IGND Tstg Rating -0.5 to 7.0 -0.5 to 7.0 -0.5 to 7.0 -50 128 180 100 -65 to 150 Unit V V V mA mA mW mA C
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).
Operating Ranges (Note)
Characteristics Supply voltage Input voltage Switch voltage Operating temperature Input rise and fall time Symbol VCC VIN VS Topr dt/dv Rating 4.5 to 5.5 0 to 5.5 0 to 5.5 -40 to 85 0 to 10 Unit V V V C 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.

On resistance
(Note 2)
RON
Note 1: Typical values are at VCC = 5 V, Ta = 25C. Note 2: Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is determined by the lower of the voltages on the two (A or B) pins.
