TC7MA2244FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA2244FK Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs The TC7MA2244FK is a high performance CMOS octal 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 over voltage tolerant inputs and outputs up to 3.6 V. This device is non-inverting 3-state buffer having four active-low output enables. When the ST input is high, the outputs are in a high impedance state. This device is designed to be used with 3-state memory address drivers, etc. Weight: 0.03 g (typ.) The 26 Ω series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge. Features • 26 Ω series resistors on outputs. • Low voltage operation: VCC = 1.8~3.6 V • High speed operation: tpd = 4.4 ns (max) (VCC = 3.0~3.6 V) tpd = 5.6 ns (max) (VCC = 2.3~2.7 V) tpd = 9.8 ns (max) (VCC = 1.8 V) • 3.6 V tolerant inputs and outputs. • 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: VSSOP (US) • Power down protection is provided on all inputs and outputs. • Supports live insertion/withdrawal (*) *: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. 1 2007-10-19 TC7MA2244FK Pin Assignment (top view) IEC Logic Level 1OE 1 20 VCC 1A1 2 19 2OE 2Y4 3 18 1Y1 1A2 4 17 2A4 2Y3 5 16 1Y2 1A3 6 15 2A3 2OE 2Y2 7 14 1Y3 1A4 8 13 2A2 2Y1 9 12 1Y4 2A1 2A2 2A3 2A4 GND 10 11 2A1 1OE 1A1 1A2 1A3 1A4 1 EN 2 4 6 8 19 18 16 14 12 1Y1 1Y2 1Y3 1Y4 EN 11 13 15 17 9 7 5 3 2Y1 2Y2 2Y3 2Y4 Truth Table Inputs Outputs OE An L L L L H H H X Z X: Don’t care Z: High impedance Absolute Maximum Ratings (Note 1) Characteristics Symbol Rating Unit Power supply voltage VCC −0.5~4.6 V DC input voltage VIN −0.5~4.6 V DC output voltage VOUT −0.5~4.6 (Note 2) −0.5~VCC + 0.5 (Note 3) V Input diode current IIK −50 Output diode current IOK ±50 DC output current IOUT ±50 mA Power dissipation PD 180 mW ICC/IGND ±100 mA Tstg −65~150 °C DC VCC/ground current Storage temperature mA (Note 4) mA 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).
