TC74VCXH16646FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXH16646FT Low-Voltage 16-Bit Bus Transceiver/Register with Bushold The TC74VCXH16646FT 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 A, B 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. Weight: 0.25 g (typ.) Features (Note) • 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 = 2.9 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 3.5 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 7.0 ns (max) (VCC = 1.8 V) • 3.6-V tolerant control inputs • Output current : IOH/IOL = ±24 mA (min) (VCC = 3.0 V) : IOH/IOL = ±18 mA (min) (VCC = 2.3 V) : IOH/IOL = ±6 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 TC74VCXH16646FT Pin Assignment (top view) IEC Logic Symbol 1DIR 1 56 1OE 1CAB 2 55 1CBA 1SAB 3 54 1SBA GND 4 53 GND 1A1 5 52 1B1 1A2 6 51 1B2 VCC 7 50 VCC 1A3 8 49 1B3 9 48 1B4 1A5 10 47 1B5 GND 11 46 GND 1A4 1A6 12 45 1B6 1A7 13 44 1B7 1A8 14 43 1B8 2A1 15 42 2B1 2A2 16 41 2B2 2A3 17 40 2B3 GND 18 39 GND 2A4 19 38 2B4 2A5 20 37 2B5 1OE 1DIR 1CBA 1SBA 1CAB 1SAB 2OE 2DIR 2CBA 2SBA 2CAB 2SAB 1A1 56 1 55 54 2 3 29 28 30 31 27 26 5 G3 3EN1 (BA) 3EN2 (AB) C4 G5 C6 G7 G10 10EN8 (BA) 10EN9 (AB) C11 G12 C13 G14 > 1 1 6D 1 1A2 1A3 1A4 1A5 1A6 1A7 1A8 2A1 2A6 21 36 2B6 VCC 22 35 VCC 2A7 23 34 2B7 2A8 24 33 2B8 GND 25 32 GND 2SAB 26 31 2SBA 2A4 2CAB 27 30 2CBA 2A5 2DIR 28 29 2OE 2A6 5 4D 5 7 > 1 7 2 52 1 6 51 8 49 9 48 10 47 12 45 13 44 14 43 15 > 1 8 12 1B1 11D 42 1B2 1B3 1B4 1B5 1B6 1B7 1B8 2B1 12 1 14 > 1 9 14 1 13D 2A2 2A3 2A7 2A8 2 16 41 17 40 19 38 20 37 21 36 23 34 24 33 2B2 2B3 2B4 2B5 2B6 2B7 2B8 2007-10-19 TC74VCXH16646FT Truth Table Control Inputs OE H DIR CAB CBA SAB SBA X* X* X X X X X X* L X* L X X* L X X* H X H X* X* X* X* X* L Bus H X X L X L X H X H L X* X* X* 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 Function The output functions of A and B Busses are disabled.
