| TC74VCX16835FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16835FT Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs The TC74VCX16835FT is a high-performance CMOS 18-bit universal bus driver. 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. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is high. When LE is low, the A data is Weight: 0.25 g (typ.) latched if the clock (CK) input is held at a high or low logic level. If LE is low, the A data is stored in the latch/flip-flop on the low-to-high transition of CK. When OE is high, the outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge. Features * * Low-voltage operation: VCC = 1.8 to 3.6 V High-speed operation: tpd = 3.3 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.2 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 8.4 ns (max) (VCC = 1.8 V) * 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 3.6-V tolerant function and power-down protection is provided on all inputs and outputs 1 2007-10-19 TC74VCX16835FT Pin Assignment (top view) OE IEC Logic Symbol 27 30 28 EN1 2C3 C3 G2 NC NC Y1 GND Y2 Y3 VCC Y4 Y5 1 2 3 4 5 6 7 8 9 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 GND NC A1 GND A2 A3 VCC A4 A5 A6 GND A7 A8 A9 A10 A11 A12 GND A13 A14 A15 VCC A16 A17 GND A18 CK GND CK LE Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Y9 Y10 Y11 Y12 Y13 Y14 Y15 Y16 Y17 Y18 3 5 6 8 9 10 12 13 14 15 16 17 19 20 21 23 24 26 1 1 3D 54 52 51 49 48 47 45 44 43 42 41 40 38 37 36 34 33 31 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 Y6 10 GND 11 Y7 12 Y8 13 Y9 14 Y10 15 Y11 16 Y12 17 GND 18 Y13 19 Y14 20 Y15 21 VCC 22 Y16 23 Y17 24 GND 25 Y18 26 OE 27 LE 28 2 2007-10-19 TC74VCX16835FT Truth Table Inputs OE H L L L L L LE X H H L L L CK X X X A X L H L H Outputs Y Z L H L H Y0 (Note) Y0 (Note) H X L L L X X: Don't care Z: High impedance Note: Output level before the indicated steady-state input conditions were established, provided that CK was high or low before LE went low.

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).
