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-Ω 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-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 = 3.8 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. Damage may result. 1 2007-10-19 TC74VCXHR162652FT Pin Assignment (top view) IEC Logic Symbol 1OEAB 1 56 1OEBA 1CAB 2 55 1CBA 1SAB 3 54 1CBA 1SBA 1SBA GND 4 53 GND 1A1 5 52 1B1 1A2 6 51 1B2 VCC 7 50 VCC 1A3 8 49 1B3 1A4 1OEBA 1OEAB 9 48 1B4 1A5 10 47 1B5 GND 11 46 GND 1A6 12 45 1B6 1CAB 1SAB 2OEBA 2OEAB 2CBA 2SBA 2CAB 2SAB 1A1 55 54 2 3 29 28 30 31 27 26 EN1 (BA) EN2 (AB) C3 G4 C5 G6 EN7 (BA) EN8 (AB) C9 G10 C11 G12 > 1 4 5 1A2 44 1B7 1A8 14 43 1B8 2A1 15 42 2B1 1A5 2A2 16 41 2B2 1A6 2A3 17 40 2B3 GND 18 39 GND 1A4 1A7 1A8 2A5 20 37 2B5 2A6 21 36 2B6 VCC 22 35 VCC 2A7 23 34 2B7 2A8 24 33 2B8 GND 25 32 GND 2SAB 26 31 2SBA 2CAB 27 30 2CBA 2A6 2OEAB 28 29 2OEBA 2A7 6 > 1 6 2 51 8 49 9 48 10 47 12 45 13 44 14 43 > 1 10 15 7 2A3 2A4 2A5 2A8 2 1B1 9D 42 1B2 1B3 1B4 1B5 1B6 1B7 1B8 2B1 10 1 > 1 12 11D 1 12 2A2 52 6 2B4 2A1 3D 4 1 1 1 1A7 13 38 1 5D 1A3 2A4 19 56 8 16 41 17 40 19 38 20 37 21 36 23 34 24 33 2B2 2B3 2B4 2B5 2B6 2B7 2B8 2007-10-19 TC74VCXHR162652FT Truth Table Control Inputs OEAB L OEBA CAB CBA SAB SBA X* X* X X X X H X* H X* X X* L X X* H X X* X* X* X* H X X L X L X H X H L X* X* X* H L H X* L Bus L X* X* H H A B Input Input Z Z X X Input Output L L H H L L H H X Qn L L H H Output Input L L H H L L H H Qn X L L H H Output Output Qn Qn Function The output functions of A and B Busses are disabled.
