1 / 12 page TC74VCX162821FT 2007-10-19 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX162821FT Low-Voltage 20-Bit D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs The TC74VCX162821FT is a high-performance CMOS 20-bit 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 overvoltage tolerant inputs and outputs up to 3.6 V. The device is byte controlled with each byte functioning identically, but independent of the other. Control pins can be shorted together to obtain full 20-bit operation. The following description applies to each byte. The twenty flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CK) transition. When the OE 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. 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 to 3.6 V • High-speed operation: tpd = 4.4 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 5.8 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.8 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 • 3.6-V tolerant function and power-down protection provided on all inputs and outputs Weight: 0.25 g (typ.) |
