TC7SBL384AFU TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7SBL384AFU Single Low-Voltage Bus Switch The TC7SBL384AFU is a low ON-resistance, high-speed CMOS 1-bit bus switch with low-voltage operation. The low ON-resistance of the switch allows connections to be made with minimal propagation delay. The device comprises a single-bit low-impedance switch with output-enable ( OE ) input. 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. P-MOS and N-MOS channel blocks also render the device suitable for analog signal transmission. All inputs are equipped with protection circuits to guard against static discharge. Weight: 0.006 g (typ.)

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).
