TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3244AFT, TC7MBL3244AFK
Octal Low Voltage Bus Switch
The TC7MBL3244A provides eight bits of low-voltage,
high-speed bus switching in a standard ’244 device pinout. The
low ON-resistance of the switch allows connections to be made
with minimal propagation delay and while maintaining CMOS
low power dissipation.
TC7MBL3244AFT
The device comprises two 4-bit low-impedance switches with
separate output-enable ( OE ) inputs. When OE is low, the switch
is on and data can flow from port A to port B, or vice versa. When
OE is high, the switch is open and a high-impedance state exists
between the two ports.
All inputs are equipped with protection circuits to guard
against static discharge.

Note: Exceeding any of the absolute maximum ratings, even briefly, may 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 from the source (zero output impedance).
