TC74VCX244FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX244FT, TC74VCX244FK Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs The TC74VCX244 is a high performance CMOS octal bus buffer TC74VCX244FT which is guaranteed to operate from 1.2 V to 3.6 V. Designed for use in 1.5 V, 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 two active-low output enables. 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. All inputs are equipped with protection circuits against static TC74VCX244FK discharge. Features Low voltage operation: VCC = 1.2 to 3.6 V High speed operation: tpd = 3.5 ns (max) (VCC = 3.0 to 3.6 V) tpd = 4.2 ns (max) (VCC = 2.3 to 2.7 V) tpd = 8.4 ns (max) (VCC = 1.65 to 1.95 V) tpd = 16.8 ns (max) (VCC = 1.4 to 1.6 V) Weight tpd = 42.0 ns (max) (VCC = 1.2 V) TSSOP20-P-0044-0.65A : 0.08 g (typ.) Output current: IOH/IOL = 24 mA (min) (VCC = 3.0 V) VSSOP20-P-0030-0.50 : 0.03 g (typ.) IOH/IOL = 18 mA (min) (VCC = 2.3 V) IOH/IOL = 6 mA (min) (VCC = 1.65 V) IOH/IOL = 2 mA (min) (VCC = 1.4 V) Latch-up performance: -300 mA ESD performance: Machine model 200 V Human body model 2000 V Package: TSSOP and VSSOP (US) 3.6 V tolerant inputs and outputs. Power down protection is provided on all inputs and outputs.
