TC7MP245FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MP245FK, TC7MP245FTG Low-Voltage/Low-Power Octal Bus Transceiver with Bus-hold The TC7MP245 is a high-performance CMOS octal bus transceiver. By a low power consumption circuit, power consumption has been reduced when a bus terminal is disable state (OE=High). The direction of data transmission is determined by the level of the DIR input. The OE input can be used to disable the device so that the busses are effectively isolated. But, bus of a B bus side at floating state is maintained in an appropriate logic level due to a bus hold circuit to a B bus. Moreover, the bus-hold circuit which is added to a B bus is off when OE is low. All inputs are equipped with protection circuits against static discharge.

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).
