TC7MBD3245AFK(SPL) Toshiba

TC7MBD3245AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MBD3245AFK Octal Bus Switch The TC7MBD3245AFK provides eight bits of high-speed TTL-compatible bus switching in a standard 245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one 8-bit switch. When output enable (OE) is low, the switch is on and port A is connected to port B. When OE is high, the switch is open and a high-impedance state exists between the two ports. The device is enable to realize the shift of signal level from 5 V to 3.3 V. All inputs are equipped with protection circuits against static Weight: 0.03 g (typ.) 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).
