TOSHIBA TC7MB3253FT

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.

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).

Note: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay
other than the RC delay of the typical on resistance of the switch and the 50 pF load capacitance, when driven
by an ideal voltage the source (zero output impedance).
