TC74VCXH162374FT TENTATIVE TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXH162374FT Low-Voltage 16-Bit D-Type Flip-Flop with Bushold The TC74VCXH162374FT is a high-performance CMOS 16-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. This 16-bit D-type flip-flop is controlled by a clock input (CK) and a output enable input (OE) which are common to each byte. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. 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. The D data inputs include active bushold circuitry, eliminating the need for external pull-up resisisors to hold unused or floating Weight: 0.25 g (typ.) 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 = 3.4 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.8 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 6.0 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 · Package: TSSOP (thin shrink small outline package) · 3.6-V tolerant function and power-down protection control inputs and outputs : Human body model > ±2000 V 1 2001-10-16 TC74VCXH162374FT Pin Assignment (top view) 1OE 1 IEC Logic Symbol 48 2CK 1 48 24 25 1EN C1 2EN C2 1D1 1D2 1D3 1D4 1D5 1D6 1D7 1D8 2D1 2D2 2D3 2D4 2D5 2D6 2D7 2D8 47 46 44 43 41 40 38 37 36 35 33 32 30 29 27 26 1D 1 2D 2 1OE 1CK 1CK 1Q1 2 47 1D1 1Q2 3 46 1D2 GND 4 45 GND 1Q3 5 44 1D3 1Q4 6 43 1D4 VCC 7 42 VCC 1Q5 8 41 1D5 1Q6 9 40 1D6 GND 10 39 GND 1Q7 11 38 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 2CK 2OE 2OE 2 2 3 5 6 8 9 11 12 13 14 16 17 19 20 22 23 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 2001-10-16 TC74VCXH162374FT Truth Table Inputs Outputs 1OE 1CK 1D1-1D8 1Q1-1Q8 H X X Z X Qn L L L L L H H Inputs Outputs 2OE 2CK 2D1-2D8 2Q1-2Q8 H X X Z L X Qn L L L L H H X: Don’t care Z: High impedance Qn: No change System Diagram 48 1D1 47 1D2 46 1D3 44 1D4 43 1D5 41 1D6 40 1D7 38 1D8 37 D D D D D D D D CK Q CK Q CK Q CK Q CK Q CK Q CK Q CK Q 2 3 5 6 8 9 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1CK 1 1OE 25 11 12 1Q8 2D1 36 2D2 35 2D3 33 2D4 32 2D5 30 2D6 29 2D7 27 2D8 26 D D D D D D D D CK Q CK Q CK Q CK Q CK Q CK Q CK Q CK Q 2CK 24 2OE 13 2Q1 14 2Q2 16 17 2Q3 3 2Q4 19 2Q5 20 2Q6 22 2Q7 23 2Q8 2001-10-16 TC74VCXH162374FT Maximum Ratings Characteristics Power supply voltage DC input voltage Symbol Rating Unit VCC -0.5 to 4.6 V ( OE , CK) VIN (An) -0.5 to 4.6 -0.5 to VCC + 0.5 V -0.5 to 4.6 (Note 1) DC output voltage VOUT -0.5 to VCC + 0.5 V (Note 2) Input diode current IIK -50 Output diode current IOK ±50 Output current IOUT ±50 mA PD 400 mW ICC/IGND ±100 mA Tstg -65 to 150 °C Power dissipation DC VCC/ground current per supply pin Storage temperature mA (Note 3) mA Note 1: OFF state Note 2: High or low state.
