TC7MBL3245CFT/FK/FTG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3245CFT, TC7MBL3245CFK, TC7MBL3245CFTG
Low Voltage/Low Capacitance Octal Bus Switch
The TC7MBL3245C is a Low Voltage/Low Capacitance CMOS 8bit Bus Switch. The low on-resistance of the switch allows connections to be made with minimal propagation delay time. The TC7MBL3245C requires the output enable ( OE ) input to be set high to place the output into the high impedance. 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).

Rise and Fall Times (tr / tf) of the TC7MBL3245C I/O Signals
The tr(out) and tf(out) values of the output signals are affected by the CR time constant of the input, which consists of the switch terminal capacitance (CI/O) and the on-resistance (RON) of the input. In practice, the tr(out) and tf(out) values are also affected by the circuit's capacitance and resistance components other than those of the TC7MBL3245C.
The tr(out) / tf(out) values can be approximated as follows. (Figure 3 shows the test circuit.) tr(out) / tf(out) (approx) = - ( CI/O + CL ) (RDRIVE+ RON) ln ( ( ( VOH - VOL ) - VM) / ( VOH - VOL ) ) where, RDRIVE is the output impedance of the previous-stage circuit. Calculation example: tr(out) (approx) = - ( 7.5 + 15 )E-12 ( 120 + 6.5) ln ( ( ( 3.0 - 0 ) - 1.5 ) / ( 3.0 - 0 ) ) 2.0 ns Calculation conditions: VCC = 3.0V , CL = 15pF , RDRIVE = 120(output impedance of the previous IC), VM = 1.5V (VCC / 2) Output of the previous IC = digital (i.e., high-level voltage = VCC; low-level voltage = GND)
