TC74VCXH162373FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXH162373FT Low-Voltage 16-Bit D-Type Latch with Bushold The TC74VCXH162373FT is a high-performance CMOS 16-bit 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. This 16-bit D-type latch is controlled by a latch enable input (LE) and an output enable input ( OE ) which are common to each byte. It can be used as two 8-bit latches or one 16-bit latch. When the OE input is high, the outputs are in a high-impedance state. The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor. Weight: 0.25 g (typ.) The D data inputs include active bushold circuitry, 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 • 26-Ω 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 = 3.3 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.5 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 5.8 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 control inputs and outputs 1 2007-10-19 TC74VCXH162373FT Pin Assignment (top view) 1OE 1 IEC Logic Symbol 48 1OE 1LE 1LE 1Q1 2 47 1D1 1Q2 3 46 1D2 GND 4 45 GND 1Q3 5 44 6 43 1D4 VCC 7 42 VCC 1Q6 8 9 GND 10 1Q7 11 41 40 39 38 1D1 1D2 1D3 1D4 1D5 1D6 1D7 1D5 1D8 2D1 1D6 2D2 GND 2D3 2D4 1D7 1Q8 12 37 1D8 2Q1 13 36 2D1 2Q2 14 35 2D2 GND 15 34 GND 2Q3 16 33 2D3 2Q4 17 32 2D4 VCC 18 31 VCC 2Q5 19 30 2D5 2Q6 20 29 2D6 GND 21 28 GND 2Q7 22 27 2D7 2Q8 23 26 2D8 24 25 2LE 2OE 2LE 1D3 1Q4 1Q5 2OE 2D5 2D6 2D7 2D8 2 1 48 24 25 47 46 1EN C3 2EN C4 3D 1 2 3 44 5 43 6 41 8 40 9 38 11 37 12 36 35 4D 2 13 14 33 16 32 17 30 19 29 20 27 22 26 23 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 2007-10-19 TC74VCXH162373FT Truth Table Inputs Outputs 1OE 1LE 1D1-1D8 1Q1-1Q8 H X X Z L L X Qn L H L L L H H H Inputs Outputs 2OE 2LE 2D1-2D8 2Q1-2Q8 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 input is taken to a low logic level.
