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) Characteristic Symbol Rating Unit Power supply voltage VCC 4.0 to 5.5 V Control pin input voltage ( OE ) V IN 0 to 5.5 V Switch I/O voltage VS 0 to 5.5 V Operating temperature Topr −40 to 85 °C Input rise and fall time dt/dv 0 to 10 ns/V Note: The operating ranges must be maintained to ensure the normal operation of the device. Unused control pin inputs must be tied to either VCC or GND. Leave unused switch I/O pins open.

TC7MB3244C,3245CFT/FK/FTG 2014-03-01 8 Rise and Fall Times (tr / tf) of the TC7MB3244C,3245C 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 TC7MB3244C,3245C. The tr / tf (out) values can be approximated as follows. (Figure 3 shows the test circuit.) tr / tf out (approx) = - ( CI/O + CL ) ･ (R DRIVE+ RON) ･ ln ( ( ( V OH – VOL ) – VM) / ( VOH – VOL ) ) where, RDRIVE is the output impedance of the previous-stage circuit. Calculation example: ≈ 1.9 ns Calculation conditions: V CC = 4.5V , CL = 15pF , RDRIVE = 120Ω(output impedance of the previous IC), VM = 2.25V (VCC / 2) Output of the previous IC = digital (i.e., high-level voltage = VCC; low-level voltage = GND) VCC Parameter 5.0 ± 0.5 V VM V CC / 2 Figure 3 Test Circuit Measure CL TC7MB3244C TC7MB3245C RDRIVE Previous IC Bn/An RDRIVE = output impedance of the previous IC VOL VOH VMVM Measure CL RDRIVE Previous IC RDRIVE = output impedance of the previous IC VCC GND Waveform generated without the TC7MB3244C,3245C Waveform generated with the TC7MB3244C,3245C added An/Bn CI/O (Switch On) RON tr out tf out
