| TC7MA2573FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA2573FK Low-Voltage Octal D-Type Latch with 3.6 V Tolerant Inputs and Outputs The TC7MA2573FK is a high performance CMOS octal D-type latch. 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 8 bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE). When the OE input is high, the eight outputs are in a high impedance state. The 26 series resistor helps reducing output overshoot and undershoot without external resistor. Weight: 0.03 g (typ.) All inputs are equipped with protection circuits against static discharge. Features * * * 26 series resistors on outputs. Low voltage operation: VCC = 1.8~3.6 V High speed operation: tpd = 5.1 ns (max) (VCC = 3.0~3.6 V) tpd = 6.1 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. 1 2007-10-19 TC7MA2573FK Pin Assignment (top view) IEC Logic Level OE LE 1 11 EN C1 OE D0 D1 D2 D3 D4 D5 D6 D7 1 2 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 VCC Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 LE D0 D1 D2 D3 D4 D5 D6 D7 2 3 4 5 6 7 8 9 1D 19 18 17 16 15 14 13 12 Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 GND 10 Truth Table Inputs Outputs D X X L H Z Qn L H OE H L L L LE X L H H X: Don't care Z: High impedance Qn: Q outputs are latched at the time when the LE inputs is taken to a low logic level.

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).
