Quad Low Voltage/Low Capacitance Bus Switch
TC7MBL6125S/6126S is low voltage CMOS 4-bit Bus Switch. The low on resistance of the switch allows connections to be made with minimal propagation delay and while maintaining CMOS low power dissipation. The TC7MBL6125S requires the output enable ( OE ) input to be set high to place the output into the high impedance state, whereas the TC7MBL6126S requires the output enable (OE) input to be set low to place the output into high impedance. All inputs are equipped with protection circuits against static discharge. TC7MBL6125SFT, TC74MBL6126SFT

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 TC7MBL6125S,6126S 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 TC7MBL6125S,6126S.
The tr / tf (out) values can be approximated as follows. (Figure 3 shows the test circuit.) tr / 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) = - ( 12 + 15 )E-12 ( 120 + 9) ln ( ( ( 3.0 - 0 ) - 1.5 ) / ( 3.0 - 0 ) ) 2.4 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)
