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 1 20 VCC D0 2 19 Q0 D1 3 18 Q1 D2 4 17 5 16 Q3 D4 6 15 Q4 D5 7 14 Q5 D1 D2 D3 D6 8 13 9 12 Q7 GND 10 11 LE D7 D4 D5 D6 Q6 EN C1 2 D0 Q2 D3 1 11 OE LE D7 19 1D 3 18 4 17 5 16 6 15 7 14 8 13 9 12 Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Truth Table Inputs Outputs OE LE D H X X Z L L X Qn L H L L L H 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).
