| TC74VCX2125FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX2125FT,TC74VCX2125FK Low Voltage Quad Bus Buffer with 3.6-V Tolerant Inputs and Outputs The TC74VCX2125FT/FK is a high-performance CMOS quad bus buffer. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. This device requires the 3-state control input OE to be set high to place the output into the high-impedance state. The 26--series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge. TC74VCX2125FT TC74VCX2125FK Features * * * 26--series resistos on outputs. Low-voltage operation: VCC = 1.8 to 3.6 V High-speed operation: tpd = 3.7 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.8 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.6 ns (max) (VCC = 1.8 V) * Output current : IOH/IOL = 12 mA (min) (VCC = 3.0 V) : IOH/IOL = 8 mA (min) (VCC = 2.3 V) : IOH/IOL = 4 mA (min) (VCC = 1.8 V) * * * * Latch-up performance: -300 mA ESD performance: Machine model 200 V Human body model 2000 V Package: TSSOP and VSSOP (US) 3.6-V tolerant function and power-down protection provided on all inputs and outputs Weight TSSOP14-P-0044-0.65A VSSOP14-P-0030-0.50 : 0.06 g (typ.) : 0.02 g (typ.) 1 2007-10-19 TC74VCX2125FT/FK Pin Assignment (top view) IEC Logic Symbol 1OE 1OE 1A 1Y 2OE 2A 2Y GND 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC 1A 2OE 4OE 4A 4Y 2A 3OE 3A 4OE 3OE 3A 3Y 4A 1 2 4 5 10 9 13 12 EN 3 6 8 11 1Y 2Y 3Y 4Y Truth Table Inputs Outputs OE H L L A X L H Y Z L H X: Don't care Z: High impedance Absolute Maximum Ratings (Note 1) Characteristics Power supply voltage DC input voltage DC output voltage Input diode current Output diode current DC output current Power dissipation DC VCC/ground current Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT PD ICC/IGND Tstg Rating -0.5 to 4.6 -0.5 to 4.6 -0.5 to 4.6 (Note 2) -0.5 to VCC + 0.5 Unit V V V mA (Note 4) mA mA mW mA C (Note 3) -50 50 50 180 100 -65 to 150 Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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).
