| TC7MA2574FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA2574FK Low-Voltage Octal D-Type Flip-Flop with 3.6 V Tolerant Inputs and Outputs The TC7MA2574FK is a high performance CMOS octal D-type flip-flop. 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 flip-flop is controlled by a clock input (CK) 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 Weight: 0.03 g (typ.) undershoot without external resistor. 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 = 6.2 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 (US20) 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. * * * * * * * 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
