| TC7SP3125TU TOSHIBA Digital Integrated Circuit Silicon Monolithic TC7SP3125TU Low Voltage/Low Power 1-Bit Dual Supply Bus Buffer The TC7SP3125 is a dual supply, advanced high-speed CMOS 1-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. Weight: 0.007 g (typ.) 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. Features (Note) * * Level converter for interfacing 1.2-V to 1.8-V, 1.2-V to 2.5-V, 1.2-V to 3.3-V, 1.5-V to 2.5-V, 1.5-V to 3.3-V, 1.8-V to 2.5-V, 1.8-V to 3.3-V or 2.5 V to 3.3-V system. High-speed operation : tpd = 6.8 ns (max) (VCCA = 2.5 0.2 V, VCCB = 3.3 0.3 V) tpd = 7.8 ns (max) (VCCA = 1.8 0.15 V, VCCB = 3.3 0.3 V) tpd = 8.6 ns (max) (VCCA = 1.5 0.1 V, VCCB = 3.3 0.3 V) tpd = 22 ns (max) (VCCA = 1.2 0.1 V, VCCB = 3.3 0.3 V) tpd = 9.5 ns (max) (VCCA = 1.8 0.15 V, VCCB = 2.5 0.2 V) tpd = 10.5 ns (max) (VCCA = 1.5 0.15 V, VCCB = 2.5 0.2 V) tpd = 23 ns (max) (VCCA = 1.2 0.15 V, VCCB = 2.5 0.2 V) tpd = 30 ns (max) (VCCA = 1.2 0.1 V, VCCB = 1.8 0.15 V) Output current : IOH/IOL = 12 mA (min) (VCC = 3.0 V) IOH/IOL = 9mA (min) (VCC = 2.3 V) IOH/IOL = 3 mA (min) (VCC = 1.65 V) Latch-up performance: -300 mA ESD performance: Machine model 200 V Human body model 2000 V Ultra-small package: UF6 Low current consumption : Using the new circuit significantly reduces current consumption when OE = "H". Suitable for battery-driven applications such as PDAs and cellular phones. 3.6-V tolerant function and power-down protection provided on all inputs and outputs. * * * * * * Note: Do not apply a signal to any bus pins when it is in the output mode.

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).
