TC74VCXHR162652FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXHR162652FT Low-Voltage 16-Bit Bus Transceiver/Register with Bushold The TC74VCXHR162652FT is a high-performance CMOS 16-bit bus transceiver/register. 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. This device is bus transceiver with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. The A, B data inputs include active bushold circuitry, Weight: 0.25 g (typ.) eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. All inputs are equipped with protection circuits against static discharge. Features (Note) * * * * 26- series resistors on outputs Low-voltage operation: VCC = 1.8 to 3.6 V Bushold on data inputs eliminating the need for external pull-up/pull-down resistors High-speed operation : tpd = 3.8 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.9 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.8 ns (max) (VCC = 1.8 V) * * 3.6-V tolerant control inputs 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 Note: Do not apply a signal to any bus pins when it is in the output mode.
