TC7WP3125FK/FC TOSHIBA Digital Integrated Circuit Silicon Monolithic TC7WP3125FK, TC7WP3125FC Low Voltage/Low Power 2-Bit Dual Supply Bus Buffer The TC7WP3125 is a dual supply, advanced high-speed CMOS 2-bit dual supply voltage interface bus buffer fabricated with silicon gate CMOS technology. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V, or 2.5-V bus and a 1.8-V, 2.5-V or 3.6-V bus in mixed 1.2-V, 1.5-V, 1.8-V or 2.5-V/1.8-V, 2.5-V or 3.6-V supply systems. The A-input interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus, the B-output with the 1.8-V, 2.5-V, 3.3-V bus. The enable input (OE) can be used to disable the device so that the signal lines are effectively isolated. All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC7WP3125FK TC7WP3125FC Weight: SSOP8-P-0.50A : 0.01 g (typ.) CSON8-P-0.4 : 0.002 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).
