TC74VCXHR162245FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXHR162245FT Low-Voltage 16-Bit Bus Transceiver with Bushold The TC74VCXHR162245FT is a high-performance CMOS 16-bit bus transceiver. 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 bus transceiver is controlled by direction control (DIR) inputs and output enable (OE) inputs which are common to each byte. It can be used as two 8-bit transceivers or one 16-bit transceiver. The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable the device so that the busses are effectively isolated. The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor. Weight: 0.25 g (typ.) The A, B data inputs include active bushold circuitry, eliminating the need for external pull-up resisisors 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 all 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 = 4.3 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 5.7 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 (thin shrink small outline package) Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. 1 2001-10-16 TC74VCXHR162245FT Pin Assignment (top view) IEC Logic Symbol 1OE 1DIR 1 48 1OE 1B1 2 47 1A1 1DIR 2DIR 25 24 1A1 47 2OE 1B2 3 46 1A2 GND 4 45 GND 1B3 5 44 1A3 48 1 G3 3 EN1 (BA) 3 EN2 (AB) G6 6 EN4 (BA) 6 EN5 (AB) 1 2 1B1 3 5 6 8 9 11 12 13 1B2 1B3 1B4 1B5 1B6 1B7 1B8 2B1 14 16 17 19 20 22 23 2B2 2B3 2B4 2B5 2B6 2B7 2B8 2 1B4 6 43 1A4 VCC 7 42 VCC 1B5 8 41 1A5 1B6 9 40 1A6 GND 10 39 GND 1B7 11 38 1A7 1B8 12 37 1A8 2B1 13 36 2A1 2B2 14 35 2A2 GND 15 34 GND 2B3 16 33 2A3 2B4 17 32 2A4 VCC 18 31 VCC 2B5 19 30 2A5 2B6 20 29 2A6 GND 21 28 GND 2B7 22 27 2A7 2B8 23 26 2A8 2DIR 24 25 2OE 1A2 1A3 1A4 1A5 1A6 1A7 1A8 2A1 46 44 43 41 40 38 37 36 2A2 2A3 2A4 2A5 2A6 2A7 2A8 35 33 32 30 29 27 26 4 5 2 2001-10-16 TC74VCXHR162245FT Truth Table Inputs Function 1DIR Bus 1A1-1A8 Bus 1B1-1B8 Outputs 1OE L L Output Input A=B L H Input Output B=A H X Z Inputs Z Function 2DIR BUS 2A1-2A8 BUS 2B1-2B8 Outputs 2OE L L Output Input A=B L H Input Output B=A H X Z Z X: Don’t care Z : High impedance System Diagram 1DIR 1 24 2DIR 48 1OE 1A1 47 25 2 1B1 13 2B1 36 2OE 2A1 1/8 3 2001-10-16 TC74VCXHR162245FT Maximum Ratings Characteristics Power supply voltage Symbol Rating Unit VCC -0.5 to 4.6 V -0.5 to 4.6 (DIR, OE ) DC input voltage VIN (An, Bn) -0.5 to VCC + 0.5 V (Note 2) DC output voltage (An, Bn) VOUT -0.5 to VCC + 0.5 V (Note 3) 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 4) mA Note 2: OFF state Note 3: High or low state.
