| TC74VCXH16245FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXH16245FT Low-Voltage 16-Bit Bus Transceiver with Bushold The TC74VCXH16245FT 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 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. 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 = 2.5 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 3.0 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 5.0 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 TC74VCXH16245FT Pin Assignment (top view) IEC Logic Symbol 1OE 1DIR 1B1 1B2 GND 1B3 1B4 VCC 1B5 1B6 1 2 3 4 5 6 7 8 9 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 1OE 1A1 1DIR 2OE 48 1 25 24 1A2 GND 1A3 1A4 VCC 1A5 1A6 GND 1A7 1A8 2A1 2A2 GND 2A3 2A4 VCC 2A5 2A6 GND 2A7 2A8 2DIR G3 3 EN1 (BA) 3 EN2 (AB) G6 6 EN4 (BA) 6 EN5 (AB) 1A1 1A2 1A3 1A4 1A5 1A6 1A7 1A8 2A1 2A2 2A3 2A4 2A5 2A6 2A7 2A8 47 46 44 43 41 40 38 37 36 35 33 32 30 29 27 26 1 2 2 3 5 6 8 9 11 12 13 14 16 17 19 20 22 23 1B1 1B2 1B3 1B4 1B5 1B6 1B7 1B8 2B1 2B2 2B3 2B4 2B5 2B6 2B7 2B8 GND 10 1B7 11 1B8 12 2B1 13 2B2 14 GND 15 2B3 16 2B4 17 VCC 18 2B5 19 2B6 20 GND 21 2B7 22 2B8 23 2DIR 24 4 5 2OE 2 2007-10-19 TC74VCXH16245FT Truth Table Inputs 1OE L L H 1DIR L H X Function Bus 1A1-1A8 Output Input Z Bus 1B1-1B8 Input Output Outputs A=B B=A Z Inputs 2OE L L H 2DIR L H X Function Bus 2A1-2A8 Output Input Z Bus 2B1-2B8 Input Output Outputs A=B B=A Z X: Don't care Z : High impedance System Diagram 1DIR 1OE 2OE 2DIR 1A1 1B1 2B1 2A1 1/8 3 2007-10-19 TC74VCXH16245FT Absolute Maximum Ratings (Note 1) Characteristics Power supply voltage (DIR, OE ) DC input voltage (An, Bn) (An, Bn) VIN Symbol VCC Rating -0.5 to 4.6 -0.5 to 4.6 -0.5 to VCC + 0.5 Unit V V (Note 2) VOUT IIK IOK IOUT PD ICC/IGND Tstg -0.5 to VCC + 0.5 DC output voltage Input diode current Output diode current Output current Power dissipation (Note 3) -50 50 50 V mA (Note 4) mA mA mW mA C 400 100 -65 to 150 DC VCC/ground current per supply pin Storage temperature Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
